Provide non-superuser predefined roles for vacuum and analyze
This provides two new predefined roles: pg_vacuum_all_tables andpg_analyze_all_tables. Roles which have been granted these roles canperform vacuum or analyse respectively on any or all tables as if theywere a superuser. This removes the need to grant superuser privilege toroles just so they can perform vacuum and/or analyze.Nathan BossartReviewed by: Bharath Rupireddy, Kyotaro Horiguchi, Stephen Frost, RobertHaas, Mark Dilger, Tom Lane, Corey Huinker, David G.
