Guys, I've been asked by a colleague about methods to keep track of 'previous' contents of a table - i.e. changes made and a way of getting back to a previous state. Now, I know INSERT/UPDATE/DELETE triggers to maintain an accompanying table is a way to do this. But, I have a nagging feeling that somebody has at one point put together such a feature in a generic fashion... I thought there was a 'time machine' module in contrib! Searches through the mailing lists have not turned up any specific pointers.
Aanyone else remember this, and remember where? Or am I misguided and deluded! Thanks, Lee. ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
