CREATE OR REPLACE FUNCTION words_toggle_puzzle(
in_mid bigint
) RETURNS table (
out_puzzle boolean
) AS
$func$
UPDATE words_moves
SET puzzle = NOT puzzle
WHERE mid = in_mid
RETURNING puzzle
INTO STRICT out_puzzle;
$func$ LANGUAGE sql;
and fails with -
ERROR: 42601: syntax error at or near "INTO"
LINE 11: INTO STRICT out_puzzle;
^
LOCATION: scanner_yyerror, scan.l:1128
