It does, for the most part. The trouble is that if we rename SERIAL
sequences to pg_xxx, and pg_dump then ignores them, then dump and
reload will fail to restore the next-serial-number state of a SERIAL
column. (Actually, given no other code changes, the serial column
would fail entirely because its underlying sequence wouldn't be
recreated at all. I was pointing out that it's not even *possible*
for pg_dump to restore the sequence's state if the sequence is given
a protected name.)

Hmm, I suppose \d ought to ignore xinv relations ...
