Description:        cannot return a setof column referenced types
Details:

Hi, I already heard from Tom Lane that this is a grammar oversight, and I
suspect it is a fairly easy fix... but to be somewhat formal I figured I'll
go ahead and fill the report:

During function creation, one cannot combine both SETOF and %TYPE.

For example:

CREATE FUNCTION temp_function() RETURNS SETOF table.column%TYPE AS %%
function_definition_here %% LANGUAGE SQL;

fails.

FYI.

Cheers!
