PostgreSQL operations, optimization, and administration. Use for: schema design, index selection, query tuning with EXPLAIN ANALYZE, postgresql.conf configuration, backup and restore (pg_dump, pg_basebackup, WAL, PITR), vacuum and autovacuum tuning, connection pooling (pgBouncer, pgPool), replication (streaming, logical), partitioning, monitoring (pg_stat_statements, pg_stat_activity), JSONB operations, full-text search (tsvector, tsquery), row-level security (RLS), extensions…
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
# PostgreSQL Operations Comprehensive PostgreSQL skill covering schema design through production operations. ## Quick Connection ```bash # Standard connection psql "postgresql://user:pass@localhost:5432/dbname" # With SSL psql "postgresql://user:pass@host:5432/dbname?sslmode=require" # Environment variables (libpq) export PGHOST=localhost PGPORT=5432 PGDATABASE=mydb PGUSER=myuser PGPASSWORD=secret psql # Connection pooling (pgBouncer default) psql "postgresql://user:pass@localhost:6432/dbname" ``` ```sql -- Check current connection SELECT current_database(), current_user, inet_server_addr(), inet_server_port(); -- Active connections SELECT count(*) FROM pg_stat_activity WHERE state = 'active'; ``` ## Index Type Selection ``` What query pattern are you optimizing? │ ├─ Equality (WHERE col = val) │ └─ B-tree (default, almost always right) │ ├─ Range (WHERE col > val, ORDER BY, BETWEEN) │ └─ B-tree │ ├─ Array/JSONB containment (@>, ?, ?|, ?&) │ └─ GIN │ ├─ Full-text search (@@) │ └─ GIN with tsvector │ ├─ Geometric/range overlap (&&, <->) │ └─ GiST │ ├─ Pattern matching (LIKE '%text%', similarity) │ └─ GIN with pg_trgm (gin_trgm_ops) │ …

How to install
mdr add 0xdarkmatter/claude-mods/postgres-ops@sha256:0859b4473d6c4bf8The line at the top of this page pins the label git:20260410.d221136, 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.
