Is it possible to downgrade PostgreSQL by a major version? If I want to upgrade a PG database from 8.x to 9.x, I have to dump the db, install the new binaries and import the dump file. This works fine going forward, but what if I need to rollback my changes? I cannot dump the 9.x database and import it with 8.x binaries, because the 9.x dump contains keywords that the old binaries don't understand (e.g. REPLICATION). I could import the original 8.x dump file again, but then I've lost any changes made when using the new binaries.
What changes, data/schema or both?
Is there a supported way to downgrade PostgreSQL by major versions?
Not that I know of.
Thank you, -Pete
