Not so's you'd notice.  PG is designed to be cross-platform, and at
the moment that means 32-bit-centric.  There's been occasional talk
of improving the performance of float8 and int8 types on 64-bit
machines, but so far it's only idle talk; and in any case I think
that performance improvements for those two datatypes wouldn't have
much effect for average applications.
