> Then the question is: does it find only #2 via polymorphic lookup, or does it think that either #1 or #2 could work (because text supports an implicit cast to citext, IIRC). If it's more than one it's an error. Not sure if the same issue exists for operators.

any errors. Hard to tell which function is being used, of course.
