PG_JOB

PG_JOB records detailed information about jobs created by users. Dedicated threads poll the system catalog PG_JOB and trigger jobs based on scheduled job execution time, and update job status in PG_JOB. This system catalog belongs to the Shared Relation category. All job records are visible to all databases.

Table 1 PG_JOB columns

Name	Type	Description
oid	oid	Row identifier (hidden attribute, which must be specified)
job_id	bigint	Job ID, primary key, unique (with a unique index)
current_postgres_pid	bigint	postgres thread ID of the job if the job has been executed. The default value is -1, indicating that the job has not yet been executed.
log_user	name	Username of the job creator
priv_user	name	Username of the job executor
dbname	name	Name of the database in which the job will be executed
node_name	name	Primary database node on which the job will be executed
job_status	"char"	Status of the job. The value can be r, s, f, or d. The default value is s. The indications are as follows: Status of job step: r=running, s=successfully finished, f=job failed, d=disable If a job fails to be executed for 16 consecutive times, job_status is automatically set to d, and no more attempt will be made on this job. Note: When you disable a scheduled task (by setting job_queue_processes to 0), the thread that monitors the job execution is not started, and the job status will not be updated. You can ignore this status. Only when the scheduled task function is enabled (job_queue_processes is not 0), the system updates the value of this column based on the real-time job status.

next_run_date	timestamp without time zone	Scheduled time of the next job execution, accurate to millisecond
failure_count	smallint	Number of times the job has started and failed. If a job fails to be executed for 16 consecutive times, no more attempt will be made on it.
interval	text	Job execution interval
last_start_date	timestamp without time zone	Start time of the last job execution, accurate to millisecond
last_end_date	timestamp without time zone	End time of the last job execution, accurate to millisecond
last_suc_date	timestamp without time zone	Start time of the last successful job execution, accurate to millisecond
this_run_date	timestamp without time zone	Start time of the ongoing job execution, accurate to millisecond
