log file

Hi All,

I have a client application that is unable to write to the database.  I
suspect a permission problem.  Is there a log file that shows the commands
that the server is executing?  Where should I start to look for it and what
controls where it is written?  Is there a way to increase/decrease the logging
level while I am troubleshooting?  I am running PostgreSQL v8rc5 on RedHat
Enterprise Linux v3.

Kind Regards,
Keith
