There is no practical way to do this in postgresql right now. What your
looking for is something reffered to as Point In Time Recovery, which
should be available in 7.4.  Since that doesn't help you now, the two
things I can think of to get around this would be to get the PITR patch
and try to apply it to 7.3 and get it to compile, or I think the Peer
Direct Company has software that can do this type of feature. Good luck,
