--- name: postgres description: | license: Apache-2.0 --- # PostgreSQL Expert Skills This skill provides comprehensive PostgreSQL expertise through specialized references. Load the appropriate reference based on the task. ## Available References ### Table Design - **[design-postgres-tables](references/design-postgres-tables.md)** — Data types, constraints, indexes, JSONB patterns, partitioning, and PostgreSQL best practices. **Use for any general table/schema design task.** - **[design-postgis-tables](references/design-postgis-tables.md)** — PostGIS spatial table design: geometry vs geography types, SRIDs, spatial indexing, and location-based query patterns. **Use when the task involves geographic or spatial data.** ### Search - **[pgvector-semantic-search](references/pgvector-semantic-search.md)** — Vector similarity search with pgvector: HNSW/IVFFlat indexes, halfvec storage, quantization, filtered search, and tuning. **Use for embeddings, RAG, or semantic search.** - **[postgres-hybrid-text-search](references/postgres-hybrid-text-search.md)** — Hybrid search combining BM25 keyword search with pgvector semantic search using RRF. **Use when combining keyword and meaning-based search.** ### TimescaleDB - **[setup-timescaledb-hypertables](references/setup-timescaledb-hypertables.md)** — Hypertable creation, compression, retention policies, continuous aggregates, and indexes. **Use when setting up TimescaleDB from scratch.** - **[find-hypertable-candidates](references/find-hypertable-candidates.md)** — SQL queries to analyze existing tables and score them for hypertable conversion. **Use when evaluating which tables to migrate.** - **[migrate-postgres-tables-to-hypertables](references/migrate-postgres-tables-to-hypertables.md)** — Step-by-step migration: partition column selection, in-place vs blue-green, validation. **Use when executing a migration.** ### Migrations - **[postgres-database-migration](references/postgres-database-migration.md)** — DDL lock reference, safe migration patterns, timeout strategies, rollback planning, and fork-based testing. **Use when planning or executing schema changes on production databases.** ### Database Management - **[ghost-database](references/ghost-database.md)** — Ghost is a managed PostgreSQL service designed for AI agents. Create, fork, pause, resume, and query databases via CLI or MCP. **Use when the user needs a database for agent workflows or wants to fork for safe experimentation.** ## How to Use 1. Identify which reference matches the user's task from the descriptions above. 2. Load the reference file to get detailed instructions and SQL patterns. 3. For tasks spanning multiple areas (e.g., "design a table with vector search"), load multiple references as needed.

supabase-postgres-best-practices
supabase/agent-skills
Postgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pg_cron, pgmq), vector/semantic search (pgvector), and restoring dumps (pg_restore) or importing data. Also load it when diagnosing slow queries, high CPU, timeouts, EXPLAIN plans, connection exhaustion, locking, bloat, or rows visible to the wrong user or tenant. This is not just a performance guide — schema, migration, security, and SQL authoring tasks need these rules too, even for a one-column change or a single query.
