pg_buffercache
F.24. pg_buffercache
The pg_buffercache module provides a means for examining what's happening in the shared buffer cache in real time.
The module provides a C function pg_buffercache_pages that returns a set of records, plus a view pg_buffercache that wraps the function for convenient use.
By default public access is revoked from both of these, just in case there are security issues lurking.
