I can't avoid it any longer and have to move an old RT2 installation to a new machine. (I'll upgrade to RT3 on that machine.)

The plan calls for a pg_dump using my workstation using CREATE the database and INSERTS (-C -D) . Then use psql to run the script created above to build the database on the new system.

I have the time to fiddle about but would appreciate any suggestions to make it run smooth(er).

O.k. :) Don't do it that way.

You want to install the new version of PostgreSQL and use the version of
pg_dump that comes with that machine.

Thanks Josh.

See my later postings. Quickly I'm using pg_dump from Pg 8.3.4 and I'm not doing the whole cluster, just selected databases.

Secondly there is no reasons to do -D (which is actually -d btw). Just
do a stock pg_dumpall.

Lastly on the new machine you will likely need to create your cluster
with --no-locale otherwise I can pretty much guarantee the restore won't
work from that far back. Alternatively you can try to cleanse the data
with something like iconv.

I'll know pretty soon.  :-)
