Roles are global to a cluster. If you do a pg_dump you will get only the
information/data for a particular database. If you do pg_dumpall you will get
the information/data for all the databases in the cluster as well as the cluster
wide information. A compromise solution is to pg_dump a particular database and
then do pg_dumpall -g which dumps only the global information. See here for more
