The current behavior doesn't violate the requirements of the standard, nor is it a regression from the behavior of any previous PostgreSQL release. What we're talking about is a request for enhancement -- to return results for cases in which the standard allows an error to be thrown. Enhancements are not applied to stable branches, and the 9.1 release has been in feature freeze for months now, so the earliest release we'd probably consider is 9.2. If there are no objections I'll add this to the TODO Wiki page with a reference to Tom's description of how it should be implemented. I didn't get the sense from the discussion that this is one which should be marked "easy" -- agreed? In the meantime, the workaround is to explicitly cast quoted literals and nulls in the result list of a set operation like UNION. -Kevin
