I usually set default privileges for user postgres like below and
create end users in particular roles, either role_ro for read only or
role_rw for read-write access. All the database objects one need the
default privileges to be applied to must be created with user
postgres.

ALTER DEFAULT PRIVILEGES FOR ROLE postgres
GRANT SELECT ON SEQUENCES TO role_ro;
ALTER DEFAULT PRIVILEGES FOR ROLE postgres
GRANT SELECT ON TABLES TO role_ro;
ALTER DEFAULT PRIVILEGES FOR ROLE postgres
GRANT EXECUTE ON FUNCTIONS TO role_ro;

ALTER DEFAULT PRIVILEGES FOR ROLE postgres
GRANT SELECT,USAGE ON SEQUENCES TO role_rw;
ALTER DEFAULT PRIVILEGES FOR ROLE postgres
GRANT SELECT,INSERT,DELETE,UPDATE ON TABLES TO role_rw;
ALTER DEFAULT PRIVILEGES FOR ROLE postgres
GRANT EXECUTE ON FUNCTIONS TO role_rw;
