Commita04dcc9

committed

From: Jan Wieck <jwieck@debis.com>

Someone changed the parser to build a TypeName node on CREATE FUNCTION in any case. As a side effect, ALL! functions created got the proretset attribute to true. Thus for a SELECT the parser wrapped an Iter node around the Expr and since singleton functions set isDone the Iter returns no tuple up.
