postgres skillA

postgres is agent-read markdown (skill) from magnus919/agent-skills: Operate PostgreSQL instances safely: configuration review, index and query-plan analysis, vacuum and bloat management, WAL archiving and point-in-time recovery, replication and failover, extensions, major-version upgrades, and evidence-based diagnostics with the bundled read-only pgdiag script. Use when running or inspecting a PostgreSQL server, diagnosing performance or backup health, or planning an upgrade or failover. Do not use for application-level data access patterns (that's backend-engin.

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 against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
