Is it needed to keep backward compatibility?
I'd like to suggest to keep pg_catalog.pg_autovacuum as a system view
even after the options is put into reloptons, and the view to be
updatable using RULEs if possible.
Current pg_autovacuum-table approach has a benefit that
we can configure options by rule, for example:
INSERT INTO pg_autovacuu SELECT ... FROM pg_class WHERE ...;
But we will not able to do that if the settings will be in reloptions
because ALTER TABLE SET cannot be used with JOINs.
