now getting log messages! - Mailing list pgsql-general

Hello Adrian,

Your suggestions have changed something and my messages are appearing in the log file.  As per your suggestion, I
enabled' log_connections' and 'log_disconnections' and restarted the server.   

I now have something to work with.  In addition, I now know what to expect when attempting to log messages (I'm a SQL
newbie).  

Thank you for your help.

Ian

Hmm.

Some suggestions:/questions:
1) Enable log_connections, log_disconnections in postgresql.conf at least temporarily. This will help you see the
sessionsyou are working in 

2) Then in the session that you do:
select * from test.testwithbasictypearguments( 1, 2::numeric, '3' );
    also do:
select 1/0;
This will help also prove the logging is tracking your session or not.

3) Are you sure you do not have another postgresql.conf in the mix that is overriding your settings?
