The two recurring failure modes are\nsemantic (geometry vs geography, SRID mismatches → wrong answers) and\nperformance (missing index usage → hour-long joins); this skill guards\nboth.\n\n## When the database is the right tool\n\nMove from files/GeoPandas to PostGIS when any of: features > a few\nmillion, concurrent readers/writers, repeated ad-hoc querying, a serving\nAPI on top, or transactional integrity needs. For single-shot analytical\nscans over GeoParquet, **DuckDB Spatial** is often the fastest\nzero-install path — same SQL mindset, no server.\n\nWhen requirements are incomplete, do not turn this heuristic into a final\nrecommendation. First obtain current and forecast data volume, concurrency,\ndelivery and mutation pattern, latency/SLA, serving needs, and operational\nownership (including backup and recovery). Define representative ingestion,\njoin, and read queries for both viable backends; compare runtime and resource\nuse only after row counts, join cardinality, SRID, geometry validity, and sample\noutputs agree. Include this benchmark and correctness plan in the current\nresponse; do not merely offer to draft it later.\n\n## Schema fundamentals\n\nThis runnable example assumes the data is contained in UTM zone 33N. Replace\nEPSG:32633 with a projected CRS verified for the actual area of interest.\n\n```sql\nCREATE TABLE parcels (\n  id          bigint GENERATED ALWAYS AS IDENTITY PRIMARY KEY,\n  parcel_no   text NOT NULL,\n  landuse     text,\n  area_m2     double precision,          -- unit in the name, always\n  geom        geometry(MultiPolygon, 32633) NOT NULL\n);\nCREATE INDEX parcels_geom_gix ON parcels USING gist (geom);\nANALYZE parcels;\n```\n\n- **Type the geometry column fully**: `geometry(MultiPolygon, SRID)` — an\n  untyped `geometry` column happily accepts mixed garbage.\n- Promote to Multi* on load (`ST_Multi`) so Polygon/MultiPolygon mixing\n  never bites.\n- **geometry vs geography**: geometry in a projected SRID for regional\n  analysis (fast, full function set); geography (SRID 4326) when the\n  extent is global/cross-zone and you want meters without picking a\n  projection (slower, smaller function set). Never store in 4326 geometry\n  and call `ST_Area` expecting m² — that's square degrees.\n- Never use EPSG:3857/Web Mercator for area or length measurement. When the\n  analysis CRS is not yet known, either use 4326 geography for a geodesic\n  result or stop and select a verified local/equal-area CRS; do not present a\n  known-distorting CRS as a runnable measurement alternative.\n- **Any stored geometry column you recommend must be typed with its SRID.**\n  Advising a \"second projected geometry column\" for repeated measurement is\n  incomplete until it is written as `geometry(<Type>, <SRID>)` with the index\n  and the populating `ST_Transform`. An untyped column recommended as a fix\n  reintroduces the mixed-SRID problem it was meant to solve:\n\n  ```sql\n  ALTER TABLE parcels ADD COLUMN geom_32633 geometry(MultiPolygon, 32633);\n  UPDATE parcels SET geom_32633 = ST_Transform(geom, 32633);\n  CREATE INDEX parcels_geom_32633_gix ON parcels USING gist (geom_32633);\n  ```\n- GiST index on every geometry column, `ANALYZE` after bulk loads; BRIN\n  only for huge, spatially-ordered, append-only tables.\n- Load paths: `ogr2ogr -f PostgreSQL`, `shp2pgsql`, or GeoPandas\n  `to_postgis` (small/medium). `COPY` beats INSERT by orders of magnitude.\n\n## Correct spatial predicates\n\n- `ST_Intersects` for \"touches at all\", `ST_Contains`/`ST_Within` for\n  containment, `ST_DWithin(a, b, dist)` for proximity — **never**\n  `ST_Distance(a,b) < dist` (that form can't use the index).\n- The classic point-in-polygon join:\n\n```sql\nSELECT p.id, a.district\nFROM points p\nJOIN admin a ON ST_Intersects(a.geom, p.geom);   -- GiST on both sides\n```\n\n- KNN nearest-neighbor with the distance operator (index-assisted):\n\n```sql\nSELECT h.id, h.name\nFROM hospitals h\nORDER BY h.geom <-> (SELECT geom FROM incident WHERE id = 42)\nLIMIT 3;\n```\n\n`<->` gives true-distance ordering on modern PostGIS for geometry; wrap\nwith `ST_DWithin` to bound the search when tables are huge.\n\n## Performance playbook\n\n1. `EXPLAIN (ANALYZE, BUFFERS)` first — confirm the GiST index is used\n   (look for \"Index Scan ... _gix\"); a Seq Scan on a big spatial join\n   means a rewrite, not a bigger server.\n2. Same SRID on both sides of every predicate — `ST_Transform` inside a\n   join predicate kills index use; store a transformed, indexed copy\n   instead.\n3. Big-polygon problem: country/basin-sized geometries make index bboxes\n   useless → `ST_Subdivide` into a work table (typical 10-100× speedup on\n   joins against them).\n\nThe following example assumes `countries(country_id, geom)`.\n\n```sql\nCREATE TABLE country_parts AS\nSELECT c.country_id, part.geom\nFROM countries AS c\nCROSS JOIN LATERAL ST_Subdivide(c.geom, 256) AS part(geom);\n\nCREATE INDEX country_parts_geom_gix ON country_parts USING gist (geom);\nANALYZE country_parts;\n```\n\n`ST_Subdivide` is a set-returning function; do not access its result as\n`(ST_Subdivide(...)).geom`.\n\n4. Validity in-database: `ST_IsValid` audit, `ST_MakeValid` repair, add a\n   `CHECK (ST_IsValid(geom))` if writers are untrusted.\n5. Simplify for serving, not for analysis: keep full-resolution geometry;\n   generate `ST_SimplifyPreserveTopology` copies or vector tiles\n   (`ST_AsMVT`) for the web tier.\n6. Batch updates in transactions; `VACUUM ANALYZE` after churn.\n\n## Common analytical patterns\n\n```sql\n-- Area-weighted aggregation (e.g., population into custom zones)\nSELECT z.zone_id,\n       SUM(b.pop * ST_Area(ST_Intersection(z.geom, b.geom)) / ST_Area(b.geom)) AS pop_est\nFROM zones z JOIN blocks b ON ST_Intersects(z.geom, b.geom)\nGROUP BY z.zone_id;\n\n-- Dissolve with attribute\nSELECT landuse, ST_Multi(ST_Union(geom))::geometry(MultiPolygon, 32633) AS geom\nFROM parcels GROUP BY landuse;\n```\n\nArea-weighted interpolation assumes uniform density within source units —\nstate that assumption when reporting. Validity repair is `ST_MakeValid`,\nnever `ST_Buffer(geom, 0)`.\n\n## DuckDB Spatial quick path\n\n```sql\nINSTALL spatial; LOAD spatial;\nSELECT a.name, count(*)\nFROM 'admin.parquet' a, 'points.parquet' p\nWHERE ST_Intersects(a.geom, p.geom)\nGROUP BY a.name;\n```\n\nReads GeoParquet/Shapefile/GPKG directly, parallel by default — ideal for\none-off large joins and pipeline steps without a server. No GiST; it plans\nits own joins — benchmark, don't assume.\n\n## Verification protocol\n\n1. Row-count accounting query after each join/overlay CTE.\n2. `SELECT DISTINCT ST_SRID(geom), GeometryType(geom)` on every table\n   touched — one query kills two classic bug families.\n3. Sample 5 output features rendered over a basemap (QGIS connects\n   directly) — numbers can pass while geometries are garbage.\n4. Treat every `sql` fence presented as runnable as a syntax and alias\n   boundary: it must execute top-to-bottom after stated schema assumptions.\n   Never put angle-bracket placeholders, ellipses, pseudocode, abandoned joins,\n   or incomplete aliases inside it. If a schema value such as an SRID is\n   unknown, ask for it or keep the template in a labeled `text` block.\n\n## Pitfalls checklist\n\n- `ST_Area`/`ST_Length` on 4326 geometry (square degrees).\n- EPSG:3857/Web Mercator for area or length measurement (systematic distortion).\n- `ST_Distance < x` instead of `ST_DWithin` (no index).\n- `ST_Transform` in join predicates.\n- Untyped geometry columns with mixed SRIDs.\n- Country-sized polygons joined without `ST_Subdivide`.\n- `buffer(0)` as validity repair (silent part loss) — `ST_MakeValid`.\n- Serving full-resolution geometries to web clients.\n\n## Execution contract\n\n- **Workflow:** inspect schema, SRID, geometry type, size, and query goal; choose predicates and indexes; write auditable CTEs; inspect the plan; reconcile results; operationalize safely.\n- **Decision rules:** use PostGIS for concurrent, repeated, or transactional spatial workloads; use file pipelines or DuckDB Spatial for bounded one-off transformations when a server adds no value.\n- **Verification protocol:** assert SRID and geometry invariants, account for rows at each join, compare indexed plans and timings, sample geometries on a map, and test boundary semantics.\n- **Failure modes:** block release for mixed SRIDs, accidental many-to-many explosion, invalid geometries, non-indexable predicates, geography/geometry unit confusion, or unexplained plan regressions.\n- **Deliverables:** self-contained parameterized SQL or migration with consistent CTE/table aliases, indexes and rationale, query plan evidence, row accounting, sample validation, expected schema, performance notes, and rollback guidance.\n- **Source freshness:** consult [the authoritative source registry](references/authoritative-sources.md) for the deployed database and extension versions before selecting functions or plans.\n","tagline":">-","category":"automation","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"Muhammed Enes Duran","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"muend/geoai-skills","creatorName":"Muhammed Enes Duran","creatorUrl":"https://github.com/muend","sourceUrl":"https://github.com/muend/geoai-skills/tree/main/skills/postgis-spatial-sql","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/muend-postgis-spatial-sql#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
