13.2 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. It also tracks the total number of rows in each table, and the last vacuum and analyze times for each table. It can also count calls to user-defined functions and the total time spent in each one.

PostgreSQL also supports reporting of the exact command currently being executed by other server processes. This is an facility independent of the collector process.
