While testing a fix for this, I observe that pg_dump is entirely broken
on the subject, because it fails to dump anything at all about the
typcollation property when dumping a base type. I also rather wonder
exactly what pg_dump would dump to restore a value of
pg_type.typcollation that's not either 0 or 100.
In short: I think this feature is quite a few bricks shy of a load yet,
and there's no point in my kluging something in citext until it settles
down more.
