When the database uses features that 3.0 does not support. For example, if a VIEW definition uses the new EXISTS operator, an older 3.0 library would not be able to parse the VIEW when it initializes. I anticipated autovacuum. So 3.0 knows about autovacuum and can read an autovacuumed file. It just can't write it. And it knows not to try.
