As part of this fix, you need to do the following:
1. Eliminate duplicates currently in the data base. This statement can be used to identify them.
SELECT e1.id id1, e2.id id2, e1.community_list_id, e1.rule_type, e1.value FROM ietf_utf8.community_rule e1 JOIN ietf_utf8.community_rule e2 ON (e1.id != e2.id AND e1.community_list_id=e2.community_list_id AND e1.rule_type=e2.rule_type AND e1.value=e2.value);
2. Delete any current duplicate lines in the text. This uses the following commands as of the check-in
DELETE FROM TABLE ietf_utf8.community_rule WHERE id=19 OR id=91 OR id=177
3. Add a constraint to the table so that it will enforce the rule itself
ALTER TABLE ietf_utf8.community_rule ADD CONSTRAINT pc_CommunityRule UNIQUE (community_list_id, rule_type, value)
