Only out of curiosity, is your current server 32 bit or 64? Are you migrating 32 to 32 or 64 to 64?

Good point. But as we stick to Linux on Intel, we expect no problems there. > But just out of curiosity: why propose against a dump/restore ?

Our PGDATA resides on a SAN, so moving/migrating the directory takes a couple of seconds. A dump/restore cycle would take much longer.
