If you refer to the ALTER SYSTEM SET patches, which I agree introduce a number of new predefined roles, it may interest you that Andrew has requested that I rework that patch set. In particular, he would like me to implement a new system of grants whereby the authority to ALTER SYSTEM SET can be granted per GUC rather than having predefined roles which hardcoded privileges.

I have not withdrawn the ALTER SYSTEM SET patches yet, as I don't know if Andrew's proposal can be made to work, but I wouldn't recommend tying this pg_maintenance idea to that set.
