<title>Monitoring Database Activity</title>
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.
