PG_JOB

PG_JOB displays detailed information about scheduled tasks created by users.

The PG_JOB view replaces the PG_JOB system catalog in earlier versions and provides forward compatibility with earlier versions. The original PG_JOB system catalog is changed to the PG_JOBS system catalog. For details about PG_JOBS, see PG_JOBS.

NOTE:
  • Note: When you disable a scheduled task (by setting job_queue_processes to 0), the thread monitor the job execution is not started, and the job_status will not be updated. You can ignore the job_status.
  • Only when the scheduled task function is enabled (that is, when job_queue_processes is not 0), the system updates the value of job_status based on the real-time job status.
