What "partial files" do you speak about? I'd like to know, as we soon
start doing WAL copies.
Incredible. You mean you make the hard link both on client and server,
and afterwards transfer with rsync? That only works for postgresql
<8.3, right? As I understand, 8.3 will reuse the space from updated
tuples and therefore lots of changes in-between will be done.
Or do you use "cluster" to sort the data before copying? But then if one
older record is deleted, all further data will have to be transfered
I'm just wondering where the savings come from.
