This makes superuser-issued REFRESH MATERIALIZED VIEW safe regardless of the object's provenance. REINDEX is an earlier example of this pattern. As a downside, functions called from materialized views must tolerate running in a security-restricted operation. CREATE MATERIALIZED VIEW need not change user ID. Nonetheless, avoid creation of materialized views that will invariably fail REFRESH by making it, too, start a security-restricted operation. Back-patch to 9.3 so materialized views have this from the beginning. Reviewed by Kevin Grittner.
