I think he wanted $PGDATA default so a remote user could find the log
location without a problem. I would prefer to see something specific in
the file name passed to identify PGDATA, but I don't have a problem with
the substitution. Thinking we have security because they can't guess
pgdata seems like security through obscurity to me.
