Hello
We are playing around with different statistics provided by postgresql
to get a better overview of our systems.
Until postgresql 8.2, and the presence of
'stats_reset_on_server_start=on' + pg_postmaster_start_time(), we could
calculate very easy many average values/sec. for our statistics.
With 8.3 and later, it is not possible to do this anymore. But we are
thinking that if we run pg_stat_reset() when the postgres server is
startet we could achieve the same.
Our question is:
Does the use of pg_stat_reset() affects the statistics autovacuum uses
to find out what to do and when this should be done? Can the use of
pg_stat_reset() affect performance in any way?
regards,
