FWIW the reason I read through this patch is that I wondered if there was anything in common with this other patch https://commitfest.postgresql.org/8/459/ -- and the answer seems to be "no". What that patch does is add a new construct TYPE(1+1) which in this case returns "int4"; I guess if we wanted to augment that functionality to cover Pavel's use case we would additionally need ELEMENTTYPE(somearray) and ARRAYTYPE(some-non-array) in the core grammar ... sounds like a hard sell.
BTW are we all agreed that enabling foo%ARRAYTYPE and foo%ELEMENTYPE in plpgsql's DECLARE section is what we want for this? -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
