Sounds good.

Please ensure the default for PL/pgSQL remains as non-scrollable. That
may or may not be the same for plpgpsm.

Default plpgpsm cursors are non scrollable too. But I have to do two patches. Syntax of declare section is total different. Between SQL/PSM and plpgsql is only one big difference (in default values). SQL/PSM procedures are flagged SECURITY DEFINER and plpgsql run wit default SECURITY CALLER.
