Usage
pgcozy: Pre-warming shared buffers according to previous pg_buffercache snapshots for PostgreSQL.
pgcozy snapshots the current shared buffer state and can later restore (pre-warm) buffers from those snapshots. Requires pg_buffercache and pg_prewarm extensions.
Initialize
Creates the pgcozy schema with a snapshots table and the cozy_type type.
Take a Snapshot
Snapshots are stored as JSONB in pgcozy.snapshots with columns: id, snapshot_date, snapshot. Each entry contains table_name, block_no, and popularity.
Warm from a Snapshot
Review Snapshots
Snapshots are stored in JSONB and can be reviewed, backed up, or transferred between servers.
