I think supporting only IDENT wouldn't be all that much of a loss. But yeah, c_expr isn't enough. We really need {a,b}_expr sans postfix expressions. I tried to create something like that earlier and found my bison grammar foo a bit rusty. Hm. I wonder if we could do a hack where we parse the a_expr ColId as a regular a_expr and then check for that in the target_el rule or in parse analysis and pull the ColId out. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Get trained by Bruce Momjian - ask me about EnterpriseDB's PostgreSQL training! ---------------------------(end of broadcast)--------------------------- TIP 1: 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
