-- - Purpose:
--   Creates the PostgreSQL tables in the Snort database neccessary to support
--   ACID.
--  
--   TABLE acid_event: cache of signature, IP, port, and classification
--                     information
--   TABLE acid_ag: stores the description of an Alert Group (AG)
-- 
--   TABLE acid_ag_alert: stores the IDs of the alerts in an Alert Group (AG)
--
--   TABLE acid_ip_cache: caches DNS and whois information
