Inspect PostgreSQL schemas or work on table design, SQL, indexes, extensions, search, or migrations. Select version-matched procedures for the actual database task.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Use the PostgreSQL procedure that owns the requested result. Establish the database version, connection scope, and relevant schemas before applying version-sensitive SQL. Read [host integration](../.shared/host-integration.md) once when using these bundled procedures. | Task | Read | |---|---| | Understand an existing database or establish query meaning | [Schema exploration](references/schema-exploration/guide.md) | | Design tables, types, keys, constraints, or indexes | [Table design](references/design-postgres-tables.md) | | Plan or perform a PostgreSQL schema migration | [Migration procedure](references/postgres-database-migration.md) | | Design spatial data with PostGIS | [PostGIS tables](references/design-postgis-tables.md) | | Implement vector similarity search with pgvector | [Vector search](references/pgvector-semantic-search.md) | | Combine keyword and semantic search | [Hybrid text search](references/postgres-hybrid-text-search.md) | | Configure an explicitly selected TimescaleDB deployment | [Hypertable setup](references/setup-timescaledb-hypertables.md) | …

How to install
mdr add dayfinggg/openai-codex-agent-skills/postgres@sha256:4a3b4975846f9a9bThe line at the top of this page pins the label git:20261029.276ae81, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
