Bug reference:      5644
Logged by:          Valentine Gogichashvili

PostgreSQL version: 9.0RC1
Operating system:   linux
Description:        Selecting ROW() in variable with 9.0 not compatible with
8.4
Details:

After migration to 9.0RC1 some stored procedures, working ok in 8.4 does not
work in 9.0.

The problem is that SELECT ROW(a,b,c) INTO var does not work any longer in
9.0.

For example:

BEGIN;

CREATE TYPE ta AS (a1 integer, a2 text);
CREATE TYPE tb AS (b1 integer, b2 ta);

DO $DOIT$

DECLARE
  a ta;
  b tb;
BEGIN

  SELECT 1, 'a' INTO a;      -- ok
  RAISE INFO 'a is %', a;

  SELECT ROW(1, 'a') INTO a; -- ok in 8.4 but fails in 9.0
  RAISE INFO 'a is %', a;


  SELECT 1, 'a' INTO b.b2;   -- ok
  RAISE INFO 'b is %', b;

END;

$DOIT$;


ROLLBACK;
