Regression tests need updating...

I committed some fixes to remove 'current' support from the date/time
types. I *think* that these are now in cvs, but I was unable to see some
of the changes (docs changes especially) when trying to get them back
from the master cvsup server. I'm a bit worried that updating cvs from
cvs.postgresql.org was not the right place to do it (but recall that it
is, so ??).

I did not update the date/time regression tests to reflect these recent
changes, having run out of time. Tom (or someone) can you please do that
for me?

TIA, and have a good Thanksgiving. I'm out of town until Monday...
