So your changes will allow these?

ALTER DATABASE foo SET (autovacuum_enabled = false);
ALTER SCHEMA foo SET (autovacuum_enabled = false);

CREATE TABLE GROUP foo_group;
ALTER TABLE foo SET TABLE GROUP foo_group;
ALTER TABLE foo2 SET TABLE GROUP foo_group;
ALTER TABLE GROUP SET (autovacuum_enabled = false);

Hopefully the grouping of tables is not purely related to AV?
