Since commit 3a9b18b309, roles with privileges of pg_signal_backend cannot signal autovacuum workers. Many users treated the ability to signal autovacuum workers as a feature instead of a bug, so we are reintroducing it via a new predefined role. Having privileges of this new role, named pg_signal_autovacuum_worker, only permits signaling autovacuum workers. It does not permit signaling other types of superuser backends. Bumps catversion.
