Right. There are a number of messages that can appear at startup before
the postmaster reads and adopts the "where to log" settings in
postgresql.conf. Those early messages are going to go to postmaster's
stderr. What it sounds like is you're using a start script that points
postmaster stderr to /var/log/postgresql/postgresql-8.3-main.log.
I don't find that to be a tremendously good idea --- in my RPMs the
early-startup messages go to a fixed file (/var/lib/pgsql/pgstartup.log)
that's not dependent on what the "where to log" configuration settings
are.
