Guides and best practices for working with Lakebase Postgres on Neon: connections, pooled vs direct, schema migrations, branching, autoscaling, scale-to-zero, instant restore, read replicas, IP allow lists, logical replication, and Lakebase Search. Use when the work is an existing DATABASE_URL, SQL, schema, inspect, or search. New backends, Auth, files, Functions, and LLM calls go to the parent `neon` skill. Also use for "@neondatabase/serverless", "@neondatabase/neon-js", "neon inspect db", "semantic search", "vector search", "full-text search", "BM25", or "hybrid search".

Lakebase Postgres

Lakebase Postgres is the database at the core of Neon. It runs on the lakebase architecture — OLTP built directly on cloud object storage — which decouples storage from compute to offer autoscaling, branching, instant restore, and scale-to-zero. It's fully compatible with Postgres and works with any language, framework, or ORM that supports Postgres.

It is the same database whether you reach it through Neon or through Databricks; this skill covers the Neon access path.

Login, users, sessions, and @neondatabase/auth belong in neon-auth.

Setup Flow

1. Select the organization and project

If a DATABASE_URL is already supplied (prompt, environment, or repo) or a .neon file points at a project, use it. Do not list organizations or create a second project for schema work.

Otherwise use the CLI (default) or MCP server to list organizations and projects. Let the user select an existing project or create a new one.

2. Get the connection string

If a DATABASE_URL is already supplied, use it. Do not fetch another through the CLI or MCP.

Otherwise use the CLI (default), neon env pull, or the MCP server to get the connection string. Store it in .env as DATABASE_URL. Read the file first before modifying it, to avoid overwriting existing values.

Web applications, serverless functionsPooled (-pooler)
Schema migrationsDirect

3. Pick the connection method and driver

Preserve the existing ORM and driver. For new TypeScript schema work with no established choice, Drizzle is a suggestion: https://neon.com/docs/guides/drizzle.md. Refer to the connection methods guide to pick the correct driver based on how the runtime treats your code: https://neon.com/docs/connect/choose-connection.md.

Driver notes:

  • On Vercel, use node-postgres (npm install pg) with Vercel Fluid compute and import { attachDatabasePool } from "@vercel/functions";
  • On Cloudflare, use node-postgres with Cloudflare Hyperdrive
  • On Neon Functions, use node-postgres, as the functions are long-running and reuse the pool across requests.
  • Use the @neondatabase/serverless driver for serverless and edge environments (for example, when using Netlify) — HTTP transport for one-shot queries, WebSocket for transaction support. Link: https://neon.com/docs/serverless/serverless-driver.md
4. Set up the schema

Manage schemas and migrations as code. Avoid running ad hoc schema migrations against your database, since they're hard to manage.

If you're using an ORM, follow your ORM's best practices to manage schemas and migrations. For example, if using Drizzle, only use Drizzle for schema and migration management unless instructed otherwise.

Branching

Use this when the user is planning isolated environments, schema migration testing, preview deployments, or branch lifecycle automation.

Key points:

  • Branches are instant, copy-on-write clones (no full data copy).
  • Each branch has its own compute endpoint.
  • Use the neon CLI or MCP server to create, inspect, and compare branches.

Link: https://neon.com/docs/introduction/branching.md

For detailed branch creation workflows (normal vs schema-only branches, reset-from-parent, CLI/MCP selection), use the neon-postgres-branches skill. If it isn't installed, fetch it from https://neon.com/docs/ai/skills/neon-postgres-branches/SKILL.md or install it with:

neon skills -s neon-postgres-branches -y

Migrations

Test a migration on a branch of production, against production-like data, before applying it to production.

Use a direct (non-pooled) connection string when you run the migration, not a pooled one. neon connection-string returns the direct string by default; make sure the hostname does not include the -pooler suffix.

Troubleshooting and Neon-Specific Performance

Use Neon's predefined, read-only diagnostics before writing catalog queries by hand. The Neon CLI neon inspect db subcommands and the Neon MCP server's inspect_database tool run the same checks.

This section covers Neon-specific diagnostic tools, compute cache behavior, and platform signals. When the evidence points to generic Postgres work such as rewriting a query, choosing an index, changing a schema, or interpreting plan nodes, load the postgres-best-practices skill and carry the diagnostic evidence into that workflow.

Docs:

Choose CLI or MCP

Prefer the Neon CLI when terminal access and authentication are available:

neon inspect db <check>

The CLI resolves the project and branch from the current Neon context. Use --project-id, --branch, and --database-name to override it. Omit --database-name to inspect every database on the branch. Use --db-url only when inspecting a Postgres database directly instead of resolving it through the Neon API.

When using Neon MCP, call inspect_database with projectId and one check. Pass branchId, databaseName, or computeId only when needed. Omit databaseName to inspect all databases on the branch. Increase limit only when the result says it was truncated.

Pick the Diagnostic
Symptom or questionChecks
Which relations consume storage?table-sizes, index-sizes
Is an index unused or a table scanned heavily?unused-indexes, seq-scans
What has run for 5+ minutes or holds locks?long-running-queries, locks
Which queries consume the most total time?outliers
Which queries run most often?calls
Does the active data fit in compute cache?lfc-hit-rate, working-set
Is autovacuum behind or is space wasted?vacuum-stats, bloat
Is logical replication healthy?replication-slots, subscriptions

Do not confuse these checks:

  • long-running-queries reports statements running right now for more than five minutes.
  • outliers ranks the top queries by cumulative execution time since statistics were reset. It does not rank by mean latency.
  • calls ranks by execution count over the same statistics history.

outliers and calls require pg_stat_statements. lfc-hit-rate and working-set require the neon extension. If a check reports a missing extension, ask before running the suggested CREATE EXTENSION statement because installing an extension modifies the database.

Interpret Results Safely
  • Treat unused-indexes as a candidate list, not permission to drop indexes. Confirm the observation window, constraints, and workload before removal.
  • A sequential scan can be correct for a small table or a query reading much of a table. Check table size, selectivity, and the query plan before adding an index.
  • bloat is a statistical estimate. Confirm the impact and plan locks or maintenance before VACUUM FULL, REINDEX, or similar remediation.
  • Cache and Postgres statistics reset when compute restarts, including scale-to-zero suspension. Run a representative workload before interpreting fresh lfc-hit-rate, working-set, vacuum-stats, or pg_stat_statements results.
  • Compute-wide checks (lfc-hit-rate, working-set, and replication-slots) run once even when inspecting every database.
  • One failing database can fail an all-databases inspection; retry the relevant check with an explicit databaseName to isolate it.
Inspect Neon Cache Behavior Per Query

Standard EXPLAIN (ANALYZE, BUFFERS) reports Postgres shared-buffer activity, but it does not show Neon's Local File Cache (LFC) or page prefetching. For a safe read-only query, add Neon's FILECACHE and PREFETCH options:

EXPLAIN (ANALYZE, BUFFERS, PREFETCH, FILECACHE)
SELECT ...;
  • File cache: hits counts pages found in the compute's LFC.
  • File cache: misses counts pages not found in the LFC and fetched from database storage.
  • Prefetch: hits, misses, expired, and duplicates show how effectively Neon fetched pages before the executor requested them.

FILECACHE and PREFETCH provide metrics for this query and do not require the neon extension. By contrast, neon inspect db lfc-hit-rate and working-set provide compute-wide statistics and do require the extension.

The MCP explain_sql_statement tool can produce a standard plan but does not expose FILECACHE or PREFETCH options. To collect those Neon-specific metrics through MCP, use run_sql with the explicit, read-only EXPLAIN statement above.

Because ANALYZE executes the statement, use it only when execution is safe; do not run it autonomously for mutating SQL. Compare cold- and warm-cache runs carefully because the first execution can populate the cache and materially change later results.

Performance Workflow
  1. Reproduce the symptom and note its time window.
  2. Run the smallest relevant inspect checks from the table above.
  3. Identify a specific query before changing schema or compute. Use MCP explain_sql_statement for a standard plan, or the Neon-specific EXPLAIN above when LFC or prefetch behavior matters.
  4. If the bottleneck is query shape, indexing, schema, locking, or vacuum behavior, load postgres-best-practices and carry forward the inspection results and query plan. Keep Neon compute, cache, connection, and platform decisions in this skill.
  5. Re-run the same check and workload to verify the change.

Use MCP list_slow_queries instead of inspect_database when the user specifically needs queries ranked by average execution time with a custom threshold and limit. Outside the explicit EXPLAIN case above, use run_sql only for read-only diagnostic SQL when the predefined checks do not answer the question.

Autoscaling

Use this when the user needs compute to scale automatically with workload and wants guidance on CU sizing and runtime behavior.

This section covers Neon-specific diagnostic tools, compute cache behavior, and platform signals. When the evidence points to generic Postgres work such as rewriting a query, choosing an index, changing a schema, or interpreting plan nodes, load the [`postgres-best-practices`](https://github.com/neondatabase/postgres-skills/tree/main/skills/postgres-best-practices) skill and carry the diagnostic evidence into that workflow.

- `pg_stat_statements`: https://neon.com/docs/extensions/pg_stat_statements.md
- Neon Local File Cache: https://neon.com/docs/extensions/neon.md

### Choose CLI or MCP

Prefer the Neon CLI when terminal access and authentication are available:

```bash
neon inspect db <check>
```

The CLI resolves the project and branch from the current Neon context. Use `--project-id`, `--branch`, and `--database-name` to override it. Omit `--database-name` to inspect every database on the branch. Use `--db-url` only when inspecting a Postgres database directly instead of resolving it through the Neon API.

### Pick the Diagnostic

| Symptom or question                            | Checks                               |
| ---------------------------------------------- | ------------------------------------ |
| Which relations consume storage?               | `table-sizes`, `index-sizes`         |
| Is an index unused or a table scanned heavily? | `unused-indexes`, `seq-scans`        |
| What has run for 5+ minutes or holds locks?    | `long-running-queries`, `locks`      |
| Which queries consume the most total time?     | `outliers`                           |
| Which queries run most often?                  | `calls`                              |
| Does the active data fit in compute cache?     | `lfc-hit-rate`, `working-set`        |
| Is autovacuum behind or is space wasted?       | `vacuum-stats`, `bloat`              |
| Is logical replication healthy?                | `replication-slots`, `subscriptions` |

Do not confuse these checks:

- `long-running-queries` reports statements running **right now** for more than five minutes.
- `outliers` ranks the top queries by cumulative execution time since statistics were reset. It does not rank by mean latency.
- `calls` ranks by execution count over the same statistics history.

`outliers` and `calls` require `pg_stat_statements`. `lfc-hit-rate` and `working-set` require the `neon` extension. If a check reports a missing extension, ask before running the suggested `CREATE EXTENSION` statement because installing an extension modifies the database.

### Interpret Results Safely

- Treat `unused-indexes` as a candidate list, not permission to drop indexes. Confirm the observation window, constraints, and workload before removal.
- A sequential scan can be correct for a small table or a query reading much of a table. Check table size, selectivity, and the query plan before adding an index.
- `bloat` is a statistical estimate. Confirm the impact and plan locks or maintenance before `VACUUM FULL`, `REINDEX`, or similar remediation.
- Cache and Postgres statistics reset when compute restarts, including scale-to-zero suspension. Run a representative workload before interpreting fresh `lfc-hit-rate`, `working-set`, `vacuum-stats`, or `pg_stat_statements` results.
- Compute-wide checks (`lfc-hit-rate`, `working-set`, and `replication-slots`) run once even when inspecting every database.
- One failing database can fail an all-databases inspection; retry the relevant check with an explicit `databaseName` to isolate it.

### Inspect Neon Cache Behavior Per Query

Standard `EXPLAIN (ANALYZE, BUFFERS)` reports Postgres shared-buffer activity, but it does not show Neon's Local File Cache (LFC) or page prefetching. For a safe read-only query, add Neon's `FILECACHE` and `PREFETCH` options:

```sql
EXPLAIN (ANALYZE, BUFFERS, PREFETCH, FILECACHE)
SELECT ...;
```

- `File cache: hits` counts pages found in the compute's LFC.
- `File cache: misses` counts pages not found in the LFC and fetched from database storage.
- `Prefetch: hits`, `misses`, `expired`, and `duplicates` show how effectively Neon fetched pages before the executor requested them.

`FILECACHE` and `PREFETCH` provide metrics for this query and do not require the `neon` extension. By contrast, `neon inspect db lfc-hit-rate` and `working-set` provide compute-wide statistics and do require the extension.

The MCP `explain_sql_statement` tool can produce a standard plan but does not expose `FILECACHE` or `PREFETCH` options. To collect those Neon-specific metrics through MCP, use `run_sql` with the explicit, read-only `EXPLAIN` statement above.

Because `ANALYZE` executes the statement, use it only when execution is safe; do not run it autonomously for mutating SQL. Compare cold- and warm-cache runs carefully because the first execution can populate the cache and materially change later results.

### Performance Workflow

1. Reproduce the symptom and note its time window.
2. Run the smallest relevant `inspect` checks from the table above.
3. Identify a specific query before changing schema or compute. Use MCP `explain_sql_statement` for a standard plan, or the Neon-specific `EXPLAIN` above when LFC or prefetch behavior matters.
4. If the bottleneck is query shape, indexing, schema, locking, or vacuum behavior, load `postgres-best-practices` and carry forward the inspection results and query plan. Keep Neon compute, cache, connection, and platform decisions in this skill.
5. Re-run the same check and workload to verify the change.

Use MCP `list_slow_queries` instead of `inspect_database` when the user specifically needs queries ranked by average execution time with a custom threshold and limit. Outside the explicit `EXPLAIN` case above, use `run_sql` only for read-only diagnostic SQL when the predefined checks do not answer the question.
