This is something we are unlikely to change, because it would have to be
a nontransactional update, which means it'd be out of sync if the ALTER
rolls back after making it.  That cure seems hardly better than the
disease.

I seem to recall some prior discussions about rearranging the
representation of sequences to allow separation of transactional and
nontransactional updates, but I don't remember if there were any
non-cosmetic reasons to do it.  This one seems pretty cosmetic ...
