It would really be nice if pg_class were altered to add two new columns: relcreatedat & relmoddat. Both would be of type timestamp. relcreatedat would contain the timestamp the object was created. Likewise, relmoddat would contain the last timestamp the object was altered / modified.
This would be very useful for user tables that are meant to exist for only a specific length of time. eg: 1 month. Then a simple: SELECT relname FROM pg_class WHERE current_timestamp::date - relcreatedat::date > 30 AND relname LIKE 'tmp_%'; Would show possible expired tables. Likewise, relmoddat would be useful for determining when someone made changes to a table, index, view, etc. Melvin Davidson - DBA Confidentiality Notice: This e-mail message (including any attached or embedded documents) is intended for the exclusive and confidential use of the individual or entity to which this message is addressed, and unless otherwise expressly indicated, is confidential and privileged information of Rackspace.
