Coalesce Quality uses the pg_monitor role by default, which reads/executes various monitoring views and functions. See more in the Postgres documentation. The following setup:
  1. Creates a dedicated user and user group for Coalesce Quality
  2. Grants the necessary permissions

​
Create a dedicated user with sufficient permissions

CREATE USER synq_user WITH PASSWORD '<password>';
CREATE ROLE synq_group;
GRANT synq_group TO synq_user;
GRANT pg_monitor TO synq_group;
On Amazon RDS / Aurora you must run GRANT pg_monitor TO synq_group as a user that has the rds_superuser role.

​
Grant permissions to the relevant schemas

GRANT USAGE ON SCHEMA "schema" TO synq_group;
GRANT SELECT ON ALL TABLES IN SCHEMA "schema" TO synq_group;
ALTER DEFAULT PRIVILEGES FOR ROLE "table_owner" IN SCHEMA "schema"
  GRANT SELECT ON TABLES TO synq_group;
Run these for every schema you want Coalesce Quality to monitor.
ALTER DEFAULT PRIVILEGES only affects tables created by the role you name in FOR ROLE. Set "table_owner" to the role that actually creates your tables (usually your application or migration user) — otherwise synq_group will not get SELECT on tables added in the future, and newly created tables will silently stop being monitored. If several roles create tables in the schema, repeat the statement once per owner.

​
