Dear all, I would love to have things covered, but I have inherited this setup. I am sure we will improve it, but I have to make the most with what I have got, I am afraid. I am grateful for all the help so far, I really appreciate it.
Ps I think there should be an easier way, maybe doing as follows: 1 – Dump the database online with pg_dump, while production server is still running 2 – Restore it to the new server, while old server is still online 3 – On the old server, run a query looking for all the new transactions since the last full backup. 4 – Run a pg_dump to dump only the new transactions since last backup and restore to the new server or ‘append’ to the new server. I think this should be possible to do. Thank you very much for all your support and help, really appreciated.

The problem is that a lot of people have contractual SLA's that do not allow them to take their systems down long enough to do a dump and restore upgrade.
