Here's a version 7 of the patch, which fixes these bugs and adds
opclasses for a bunch more types (timestamp, timestamptz, date, time,
timetz), courtesy of Martín Marqués. It's also been rebased to apply
cleanly on top of today's master branch.

I have also added a selectivity function, but I'm not positive that it's
very useful yet.
