pgsql: Make documentation of --help and --version options more consiste

Make documentation of --help and --version options more consistent

Before, some places didn't document the short options (-? and -V),
some documented both, some documented nothing, and they were listed in
various orders.  Now this is hopefully more consistent and complete.
