Three nologin roles with non-overlapping privs are created by default * pg_read_all_settings - read all GUCs. * pg_read_all_stats - pg_stat_*, pg_database_size(), pg_tablespace_size() * pg_stat_scan_tables - may lock/scan tables Top level role - pg_monitor includes all of the above by default, plus others Author: Dave Page Reviewed-by: Stephen Frost, Robert Haas, Peter Eisentraut, Simon Riggs
