We are in the process of migrating our various servers to
a kvm host with guest vms. The new guests run pg-9.1.2
under CentOS-6.2. However, our off site warm spares are
still running pg-8.4.4 under CentOS-5.7.
We have an automated transfer routine that dumps the live
database, now running v.9.1.2, and sends the dump file to
the off site host. There the dump is restored to an 8.4.4
version.
My question: Is their a way to specify a pg_dump option
to retain compatibility with a lower version pg database?
Alternatively, can one install a higher level pg_dump in
an otherwise 8.4.4 installation?
The reason for the question is that we are receiving these
warnings:
