pg_resqueue

note

The pg_resqueue system catalog table is valid only when resource queue-based resource management is active.

The pg_resqueue system catalog table contains information about Apache Cloudberry resource queues, which are used for the resource management feature. This table is populated only on the coordinator. This table is defined in the pg_global tablespace, meaning it is globally shared across all databases in the system.
