In that case it should be 4 or so bytes less per row. How sure are you
about your estimated row count? You are way over what I figure the
table size ought to be.

In 7.3, yes. (Before that, you paid for the space whether you wanted
'em or not.) You could shave another 4 bytes off if you created the
table without OIDs.
