Having now spent some more time looking, I believe there is a solution which makes it unreserved which does not require any significant pain in the code. I'm not entirely convinced that this is the right approach in the long term, but it might allow for a more planned transition. The absolute minimum seems to be: GROUPING as a col_name_keyword (since GROUPING(x,y,...) in the select list as a <grouping operation> looks like a function call for any argument types) CUBE, ROLLUP, SETS as unreserved_keyword -- Andrew (irc:RhodiumToad) -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
