I have a whole bunch of code that appends to an array in this way without casting ‘foo’ to text or text[]. It’s only in an exception block that it’s complaining. Hrm, looking back through my code, it looks like I’m mostly calling format() to append to an array, which of course returns a ::text, so no ambiguity. Guess that’s my issue. Thanks, David
