Hello

Does psql maintain some sort of global performance counters?

We are interested mainly in following counters (cumulative, by all psql processes):

- cpu time by all backends

- sql queries count

- fsync count

- disk reads / disk bytes read

- disk writes / disk bytes written

- transaction commit count

- client connect count

- client disconnect count

- backend start count

- backend terminate count

We intend to use these counters (their differences for fixed time periods) for monitoring and reporting purposes.

Thanks,

Cestmir Hybl
