Regarding the pg_refresh_all_matview predefined role, I don't think it's a good idea. Refreshing a materialized view doesn't seem like an administrative action to me. First, it's unbounded in time, so the admin would need to be careful to have a timeout. Second, the freshness of a materialized view seems very specific to the application, rather than something that an admin would have a blanket policy about. Thirdly, there's not a lot of information the admin could use to make decisions about when to refresh (as opposed to VACUUM/CLUSTER/REINDEX, where the stats are helpful). But I'm fine with having a grantable privilege to refresh a materialized view. It seems like the discussion on VACUUM/CLUSTER/REINDEX privileges is happening in the other thread.
