From gram.y, yes it tries to strip the INTO by skipping over some stuff,
maybe the "*" trips it ?
Anyway the syntax SELECT INTO temp1 * FROM .... should work.
On this same subject, the plpgsql doc says to use
SELECT expression INTO var FROM ...
but Bruce's book, in several examples ("PL/PGSQL Functions" for instance,
node203.html) uses
SELECT INTO var expression FROM ...
Both should work, but there may be there's something to straighten up here.
Cheers,
Florent
