For me it seems more a design problem than the length of internal number....
Why not create a table with 2 field containing int, setting the primary key
on both of them and running a sequencing scheme on both as if it was a
single number....
There are no more limitations anymore, as if you know you will need a lot of
record you may decide to use 1, 2, or 3 numbers...
Question, does postgress is able to run sequence on 2 combined numbers...
Cheers...

Is this necessarily a good solution? If you use 64-bit OIDs,
some joker
will just hook up a several-terra-byte disk array to his
machine, try to
store the location of every molecule in the universe and
break it.
Admittedly, ~2x10^20 is a very large number, but that's what
they thought
about 2000, also...
What I'm saying is, is there a better way of doing this?
