Обсуждение: Full (special) logs for specified users/hosts/etc
Hello hackers,
Consider a Postgres cluster containing several DBs (for example several projects/sites). If one wants to optimize queries on one specified site -- what should he do? His obvious need is to switch full logging for the exact database on, collect the logs and analyze them using pgFouine/pgBadger.
But currently, there is no way to specify log settings for one database / one user / one host. There are only *global* settings in postgres.conf.
We experienced this problem in various project several times already. Usually it is solved with initdb-ing separate cluster, what is annoying and difficult if you have replication installed and working.
How difficult is to implement *local* logging settings per database/user/host? Is it worth to work on for future versions?

Not exactly suitable for pgBadger, but one could setup “csvlog” format, load logs into the dedicated table and analyse with SQL statements:

I'm using this approach for quite some time.

There are only *global* settings in postgres.conf. alter database postgres set log_statement='all' alter user foo set log_statement='all' - Heikki
