pgcozy ========= pgcozy is an extension who adds the capability to keep snapshots of the buffer cache and later can prewarm according to these snapshots. Snapshots are saved in jsonb format under a schema and a table and they can be reviewed , backed up or transferred Also see my blog for some examples and tips: INSTALLATION ------------ Requirements: pg_preworm and pg_buffercache extensions In directory where you downloaded pgcozy to run make make install Log into PostgreSQL and run the following commands. CREATE EXTENSION pgcozy; select pgcozy_init(); This will create a schema called pgcozy , a table called snapshots and a type called cozy_type. This extension uses pg_prewarm and pg_buffercache to read the contents of shared buffers and store them for later prewarm.
