Right. We used to have two separate binaries, and the postmaster would
actually exec() the backend (postgres) binary for every session launch.
About two years ago, Bruce made them into a single executable so that
session launch only needs fork() and not exec(). But he kept the old
switch-parsing mechanisms for backwards compatibiliy with existing
startup scripts. So our current switch syntax is a dreadfully ugly
legacy thingy :-(
Peter E. has done some good work towards providing a less ugly switch
notation for 7.1.
