12.2 The Statistics Collector

PostgreSQL's statistics collector is a subsystem that supports collection and reporting of information about server activity. Presently, the collector can count accesses to tables and indexes in both disk-block and individual-row terms.

PostgreSQL also supports determining the exact command currently being executed by other server processes. This is an independent facility that can be enabled or disabled whether or not block-level and row-level statistics are being collected.
