You really need to think about an update.  PG 8.3.x is considered EOL
and is no longer getting updated.  What's more, the last release in
that series was 8.3.23, so you're missing about four years worth of
bug fixes.

A first guess is that the postmaster is not using the config file you
think it is.  "show config_file" might be informative about that.
You could also try
    select * from pg_settings where name = 'log_min_messages'
to see where the active setting came from.
