2 Aktions in a Rule

From

Hello,
I hope someone can help me. I Want 2 Aktions executeed in a Rule like:
CREATE RULE auftraege_neu_delete AS ON delete    TO auftraege_neu DO         (DELETE FROM auftraege_neu_positionen
WHEREauftraege_neu_positionen.auftragsnr   = OLD.auftragsnr;DELETE FROM auftraege_neu_zubehoer    WHERE
auftraege_neu_zubehoer.auftragsnr    = OLD.auftragsnr;);
 
but I get a Parser Error:
ERROR: parser: parse error at or near ""
This is in PostgreSQL 6.5.2

Has anyone the correct syntax?

regards
Florian

I have the same problem. Dox says that multiple actions are permitted
on a single rule. But it won't work. I do not know why.

There's nothing wrong with that syntax AFAICS.  Furthermore, my copy
of Postgres takes it just fine (both 6.5.2 and current sources).

I suspect you compiled with a buggy version of yacc or bison.  Postgres'
grammar is large and complex enough that it tends to expose problems
in vendor-supplied yaccs :-(.  Try getting a recent GNU bison (let's
see ... I have 1.25 installed here, it's probably not the latest)
and rebuilding.

Yep. It works.

I had the problem with 6.5.1 version both on RedHat 5.1 and FreeBSD 3.2 boxes.
It runs just fine, when is built using bison-1.28 (available at ftp.gnu.org).

Thanks all.
