pgsql: Remove incorrect entries in pg_walsummary's getopt_long call.

Remove incorrect entries in pg_walsummary's getopt_long call.

For some reason this listed "-f" and "-w" as valid switches, though
the code doesn't implement any such thing nor do the docs mention
them.  The effect of this was that if you tried to use one of these
switches, you'd get an unhelpful error message.
