Re: command

Use syslog... It's documented on the website and in the
manual... Assuming you are running on Linux then adding/editing:

 syslog = 1 # range 0-2
 syslog_facility = 'LOCAL0'
 syslog_ident = 'postgres'

to $PGDATA/postgresql.conf and:

 local0.*			/var/log/postgresql

to /etc/syslog.conf and then doing:

 /etc/init.d/syslog restart
 /etc/init.d/postgresql restart

should give you the log you're looking for at:

 /var/log/postgresql

I'll leave it to you to translate this to your flavour of UNIX (or
Linux)...
