I think that'd be a lot cleaner and simpler. It's something I've frequently wanted, and as Hekki points out it's already possible by creating the function in pg_temp, there just isn't the syntax sugar for "CREATE TEMPORARY FUNCTION". So why not just add "CREATE TEMPORARY FUNCTION"? It means two steps: CREATE TEMPORARY FUNCTION ... $$ $$; SELECT my_temp_function(blah); but I'm not personally convinced that a parameterised DO block is much easier, and the idea just rings wrong to me. I agree with Pavel that the natural way to parameterise DO blocks, down the track, will be to allow them to get (and set?) SQL-typed session variables. Of course, we'd need to support them first ;-) -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, 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
