[ raised eyebrow... ] Could we see a concrete example?
One potential issue is that, depending on which PG version and locale
and database encoding you are using, case-insensitive matching might
not work properly on non-ASCII letters. Other than that, the only
gotcha I can think of is having regexp special characters in the
substrings and failing to escape them properly.
