| `config_merge` |JSONB| - | ✖| Since 2.29.0. Merge these keys into the {C.JOB}'s existing `config` instead of replacing it. The keys you pass take precedence, and the keys you leave out are unchanged. Cannot be combined with `config`. |
| `next_start` |TIMESTAMPTZ| - | ✖ | The next time at which to run the job. The job can be paused by setting this value to `infinity`, and restarted with a value of `now()`. |
| `if_exists` |BOOLEAN| `false` | ✖ | Set to `true` to issue a notice instead of an error if the job does not exist. |
