Fwiw I already committed it. In the end I made only trivial changes the most significant of which was changing the column name to "ordinality". I found the changes I was making didn't really make much difference and were turning into bike shedding. There are two followup changes that were discussed in this thread: 1) Changing the WITH_* and NULLS_* tokens to not eat the following token if it's not used by the grammar so that it doesn't interfere with syntax like "select nulls first from t as a(nulls)". 2) Teaching the parser that the functionscan is ordered by ordinality so it can do a merge join without resorting the inputs. That would relieve the one remaining piece of functionality that multiple SRFs in the target list give over SRFs in the from list. I have patches for both of these in progress but frankly they're both stuck and I'm not likely to finish either without some advice. I'll start new threads (or already have) for them though. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
