Would a simple diff between 2 pg_dumps work if only data is being added in the database (i.e. no alters or tables are added)? So say I do a pg_dump once a day and one every 3 hrs there after and in the script I do a diff and store as a PITR dump. Will that work, or is it too simplistic?

Yeah, rsync would work, but it's just a useless extra layer of software... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
