Might as well. No point in writing more productions if it doesn't buy anything. BTW, I've forgotten whether your patch is purely syntactic or not, but I'd really like to see someone fix things so that BETWEEN has its own expression node tree type and is not expanded into some ugly "A>=B and A<=C" equivalent. This would (a) allow it to be reverse-listed reasonably, and (b) eliminate redundant evaluations of the subexpressions. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
