Re: ERROR (Bug?) in RULE processing ?

I see the query:
arbeitsdb=# CREATE RULE doc_contained AS ON INSERT TO documents WHEREarbeitsdb-# ((NEW.type = 1) AND (count( (SELECT
element_idarbeitsdb(#  FROM element_contained_in WHERE (element_id =currval('docs_seq')) )) = 0))arbeitsdb-# DO INSTEAD
NOTHING;

Added to TODO:
* Prevent aggregates from being used in rule WHERE clauses

Also, please try using HAVING with count() and see if that helps.
