pg_resqueuecapability

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

The pg_resqueuecapability system catalog table contains information about the extended attributes, or capabilities, of existing LightDB-A Database resource queues. Only resource queues that have been assigned an extended capability, such as a priority setting, are recorded in this table. This table is joined to the pg_resqueue table by resource queue object ID, and to the pg_resourcetype table by resource type ID (restypid).

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.
