Seems to be some (long standing) inconsistency in our capitalisation
of multi-word labels - eg.
lstColumns->AddColumn(_("Column name"), 90);
lstColumns->AddColumn(_("Order"), 40);
lstColumns->AddColumn(_("NULLs Order"), 50);
+ lstColumns->AddColumn(_("Op. Class"), 40);
"Column name" vs. NULLs Order" for example.
I suspect you should remove this too:
+ wxLogError(wxT("opclass:") + GetOperatorClasses());

Don't see why not.

We'd really need an implementation of CREATE OR REPLACE INDEX ...
CONCURRENTLY to do that well I think. Otherwise, we could
inadvertently cause users great pain if they don't realise a
drop/create will happen for certain changes.
