Обсуждение: reject empty string in float[48], oid

This patch changes the input routines for float4, float8 and oid to
reject empty strings (rather than treating them as "0"). In 8.0 we issue
a warning about this behavior and indicate that the input will not be
accepted by a future release, so it seems reasonable to disallow the
input in 8.1. The patch also updates the regression tests.

Barring any objections, I'll apply this to HEAD tomorrow.

If you're going to add regression tests, how about testing the case of a
non-empty-but-all-whitespace string?

AFAICS that is already tested for.

[ looks again... ]  Doh.  Maybe you should put these tests next to those
then...
