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.
