Is it possible to isolate logging for each individual database? For example, lets say I have 3 databases: db1, db2, db3. And I want to log db activity (statements, login/logout, etc..) db1, db2, db3 like $PGDATA/db1, $PGDATA/db2, $PGDATA/db3, respectively. Currently everything is logged in $PGDATA/pg_log TIA
