I haven't run into it and haven't heard anything from anyone that has but
was curious just the same... I figured that count() was using an integer but
I suppose if someone had the number of rows required to overflow it they'd
be in the overflowing OID situation too and a dysfunctional count() would
probably be the least of their worries...

Sure..

I figured that it would be a tiny number of people.. IMHO we should do it
because as the great Spock once said "The needs of the many outweigh the
needs of the few.."
