I was going to suggest exactly that.  It's not quite as simple as a
"serial" column declaration, but you can split the use of an ID sequence
generator over just as many tables as you need to have unique IDs
across.  That way you don't have a problem at dump/reload time,
and you don't exhaust your ID space any faster than you must.
