postgres skillA

postgres is agent-read markdown (skill) from timescale/pg-aiguide: Use this skill for any PostgreSQL database work — table design, indexing, data types, constraints, extensions (pgvector, PostGIS, TimescaleDB), search, and migrations. **Trigger when user asks to:** - Explore an existing PostgreSQL database to understand its objects and relationships - Design or modify PostgreSQL tables, schemas, or data models - Choose data types, constraints, indexes, or partitioning strategies - Work with pgvector embeddings, semantic search, or RAG - Set up full-text search.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.

What the file says

# PostgreSQL Expert Skills

This skill provides comprehensive PostgreSQL expertise through specialized references. Load the appropriate reference based on the task.

## Available References

### Existing Databases
- **[schema-exploration](references/schema-exploration/guide.md)** — Read-only, question-driven exploration of schemas, tables, views, routines, triggers, RLS, and extensions using `pg_catalog`. **Use to understand an existing database before designing changes or writing queries.**

### 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.**

How to install

Latest version
mdr add timescale/pg-aiguide/postgres@git:20260925.2209242
Exact content
mdr add timescale/pg-aiguide/postgres@sha256:6855e5cb7628c3ce

Pin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
