| |
| The `pg_resqueue` system catalog table contains information about HAWQ resource queues, which are used for managing resources. This table is populated only on the master. This table is defined in the `pg_global` tablespace, meaning it is globally shared across all databases in the system. |

| | `rsqname` | name | | The name of the resource queue. | |
| | `parentoid` | oid | | OID of the parent queue of the resource queue. | |
| | `activestats` | integer | | The maximum number of parallel active statements allowed for the resource queue. | |
| | `memorylimit` | text | | The maximum amount of memory that can be consumed by the resource queue (expressed as a percentage of the cluster's memory.) | |
| | `corelimit` | text | | The maximum amount of cores that can be consumed by the resource queue (expressed as a percentage of the cluster's cores.) | |
| | `resovercommit` | real | | The ratio of resource consumption overcommit for the resource queue. | |
| | `allocpolicy` | text | | The resource allocation policy name for the resource queue. | |
| | `vsegresourcequota` | text | | The virtual segment resource quota for the resource queue. | |
| | `nvsegupperlimit` | integer | | The upper limit of number of virtual segments allowed for one statement execution. | |
| | `nvseglowerlimit` | integer | | The lower limit of number of virtual segments allowed for one statement execution. | |
| | `nvsegupperlimitperseg` | real | | The upper limit of number of virtual segments allowed for one statement execution. The limit is averaged by the number of segments in the cluster. | |
| | `nvseglowerlimitperseg` | real | | The lower limit of number of virtual segments aloowed for one statement execution. The limit is averaged by the number of segments in the cluster. | |
| | `creationtime` | timestamp with time zone | | Time when the resource queue was created. | |
| | `updatetime` | timestamp with time zone | | Time when the resource queue was last changed. | |
| | `status` | text | | Current status of the resource queue.Possible values are `branch`, which indicates a branch resource queue (has children), and `NULL`, which indicates a leaf-level queue (no children). | |
