What about a separate struct passed from pg_dump's main() to the
functions that execute queries, containing a bunch of bools?  This'd
still have the problem that mindless copy and paste would cause a bug,
but I wonder if that isn't overstated: if you use the wrong flag,
pg_dump would fail as soon as you try to invoke your query when it
hasn't been prepared yet.
