Maybe what we need is not to get rid of the flat files, but to speed
them up.  If we're worried about speed in the pg_authid flatfile, and
come up with a solution to that problem, what will we do with the
pg_database flatfile when it grows too large?  We can't just get rid of
it, because autovacuum needs to access it.
