I think it is not necessary. pg_dumpall supports dumping of the entire
contents of a database cluster, It backs up each database in a given
cluster, and also *preserves cluster-wide data such as role and tablespace
definition*s. hence if you want to take backup for entire cluster then you
can directly use pg_dumpall.
or if you have any specific need then you can use pg_dump and manually
preserve/delete other database objects .
