Two answers tend to come up: a) Slony-I (which I work on; URL below) b) Londiste (originated by "Skype folks"; see also
"SkypeTools")
Slony-I has more documentation; Londiste is reputed to be a bit easier
to configure (though being somewhat documentation-light may still
leave the bar set pretty high).
