PostgreSQL version: 8.1.3
Operating system: FreeBSD 6.1
Description: perl function that returns setof composite type
Details:
The code below works fine on version 8.0.3.
However, on version 8.1.3, the last query returns
the following error:
set-valued function called in context that cannot accept a set
Hence there does not seem to be an way to use
a perl function that returns 'setof composite'
on non-constant input.

DROP TABLE num CASCADE;
CREATE TABLE num (n int);
COPY num FROM stdin;

CREATE OR REPLACE FUNCTION sqlget(num) RETURNS SETOF num AS $$
SELECT $1.n
$$ LANGUAGE SQL;
CREATE OR REPLACE FUNCTION perlget(num) RETURNS SETOF num AS $$
return [{n=>$_[0]->{n}}];
$$ LANGUAGE plperl;
SELECT (sqlget(num.*)).* FROM num;
SELECT (perlget(num.*)).* FROM num;
