I'd like to keep these tests, since they ensure not just that the
functions work but that they work with citext. Given what we found
with length() and friends not working when there was an implicit cast
to bpchar, I think it's valuable to continue to ensure that these
functions work as expected with citext. Otherwise someone in the
future might come along and make the cast to bpchar implicit again,
and no tests would fail to tell him/her otherwise.
These tests make good regressions.
Thanks,
David
