Docs for CREATE RULE with WHERE/NOTIFY - Mailing list pgsql-patches

Hello,

I've just been bitten by this:

dsuch=# CREATE RULE foorule AS ON UPDATE
dsuch-#     TO foo WHERE NEW.x = '1'
dsuch-#     DO ALSO NOTIFY bar;
ERROR:  rules with WHERE conditions may only have SELECT, INSERT,
UPDATE, or DELETE actions

Here's an explanation
http://archives.postgresql.org/pgsql-hackers/2001-11/msg00986.php,
but would you also consider applying the following tiny patch to
create_rule.sgml
to document the behaviour?

thank you,
