I think this is just a bug and not a fundamental design flaw: it looks
to me like simply removing the citext-specific declarations of the regex
operators would fix the problem (because then it'd fall back on the
standard operators with an implicit cast to text, and that would match
the index). Might cause a problem though for anybody who's got those
operators embedded in views.
