pg_dumpall is a utility which dumps the Greenplum database including global objects that are common to all databases, but when you look at the output generated by pg_dumpall you might encounter that the resource queue information is missing.
Pivotal Greenplum Database (GPDB) all versions
In order to include the resource queue details in pg_dumpall output, you would have to add the parameter "--resource-queues" along with the command.
So, the command would look like:
pg_dumpall --resource-queues
