There's no practical limit, assuming the old version is not an ancient version of PostgreSQL (pre-9.0, say).
That being said, PostgreSQL's behavior changes with every major release, and there is always the possibility of query
planchanges or other surprises. It's essential to test your application thoroughly on the target version, and do dry
runsof pg_upgrade.
