Statistics collector

A subsystem which collects information about activity on the local server

The statistics collector is a subsystem which collects information about activity on the local server, such as table/index access and vacuum/analyze activity.

Information gathered by the statistics collector is made available via the various pg_stat_* / pg_statio_* views.

Note that these kinds of statistics are specific to the local server and are not replicated. They should not be confused with the statistics on data collected by analyze operations and stored in the pg_statistic table, which are replicated.
