We don't need hasty patches.  What we need is a re-think of the division
of labor between pg_dump and pg_dumpall.  Up to now, pg_dump has only been
charged with dumping/restoring the data "inside" an individual database,
not with handling any database-level properties.  Those are the
responsibility of pg_dumpall.

I'd be the first to agree that maybe this wasn't the best design, but at
least it's consistent.  If we're going to change things, we need to start
by deciding where we're going to re-draw the line, and figuring out what
sort of impact that will have in terms of compatibility considerations
and users' backup/restore procedures.
