What is Linux doing with my changes.  Do you see all the process names
as postmaster?  Do you see the query type displayed as part of the ps
output.  We can use setproctitle/sendmail hack to change the process
name from postmaster to postgres, but are these sufficiently quick to
be run for every query to display the query type, i.e. SELECT.
