BTW, to clarify that: obviously, this loop *does* access pg_class, and
pg_class's indexes too. The issue here is that if any of these other
stanzas ever really executed, we would be doing accesses to a bunch of
other catalogs as well, meaning that their relcache entries would have to
already exist in a state valid enough to permit access. That would mean
that they'd have to be treated as bootstrap catalogs so that we could
create hardwired entries with formrdesc. That's not a direction I want
to go in. Bootstrap catalogs are a huge pain to maintain; we don't want
any more than the absolute minimum of them.
