Storage

The Postgres backend stores CCEvents and CCLog messages in distict tables named <cluster>_events and <cluster>_logs respecively. It does not make use of distinct tables to hold specific and returning parts of CCEvents and CCLog messages (namely hostname tag, type tag and typeid tag). The timestamps of the messages are stored as UNIX timestamps with precision in seconds.
