Note

    The pg_stat_resqueues view is valid only when resource queue-based resource management is active.

    The pg_stat_resqueues view allows administrators to view metrics about a resource queue’s workload over time. To allow statistics to be collected for this view, you must enable the stats_queue_level server configuration parameter on the Greenplum Database master instance. Enabling the collection of these metrics does incur a small performance penalty, as each statement submitted through a resource queue must be logged in the system catalog tables.
