The difference would be pretty marginal --- especially if you choose to
use bigints instead of ints. (A timestamp is just a float8 or bigint
under the hood, and is no more expensive to compare than those datatypes.
Timestamps *are* expensive to convert for I/O, but comparison does not
have to do that.) I wouldn't recommend kluging up your data schema just
for that.
