Any ideas what the problem could be here?
Use the pg_dump from the target (i.e. newer) pgsql. I.e. if going
from 8.3.8 to 8.4.1, use the pg_dump that comes with 8.4.1 to dump the
8.3.8 database.
Can I assume that this is even more critical if gong from 8.2 to 8.4?
I usually just do it like so:
(First migrate accounts:)
pg_dumpall --globals -h oldserver | psql -h newserver postgres
I'm a little confused here. Are you saying to used the network
connections between thetwo servers and to pipe the dumpall directly to
the psql load?
(then each database:)
createdb -h newserver dbname
Then create new databases on the the new server to match the. The
names from the old server?
pg_dump -h oldserver dbname | psql -h newserver dbname
(repeat as needed, save output for error messages)
Then dump each database individually and pipe the dump to the psql load?
These two procedures seem to duplicate the goal? Or am I mosaic
something?
