I looked through this and it seems generally OK. A minor nitpick is
that we usually write "(Datum) 0" not "(Datum) NULL" for dont-care Datum
values. A slightly bigger issue is that makeItemLikeRegex still allows
an error to be thrown from RE_compile_and_cache if a bogus regex is
presented. But that could be dealt with later.
(I wonder why this is using RE_compile_and_cache at all, really,
rather than some other API. There doesn't seem to be value in
forcing the regex into the cache at this point.)
