Worth keeping in mind that INFO messages do not normally go to the server log, but rather only to the client. If it were a problem at the server side, you could also suggest adding %p to the log line prefix to disambiguate. Maybe the scenario where this is a real problem is vacuumdb -j ... > In vacuum_rel()@vacuum.c, there are a couple of logs that could be > improved as well with the schema name. I agree that there's a lot of room for improvement there. If I'm allowed some scope creep, I'd say that gathering detailed vacuum info from both autovacuum and user-invoked vacuum in a central place would be very welcome. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
