Sorry it is a typo in the email. My readonly role is dbreadonly. It works well so far except no access to new tables created by read write role. It has access to new tables created by admin role.
I granted dbreadonly as the following:
-- Read-only role
GRANT CONNECT ON DATABASE mydatabase TO dbreadonly;
GRANT USAGE ON SCHEMA public TO dbreadonly;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO dbreadonly;
GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO dbreadonly;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO dbreadonly;

It says "dbreadonly" instead of "readonly". Just a typo or a different role?
