Shows information about runtime errors encountered by jobs run by the automation framework. This includes jobs set up for user-defined actions and jobs run by policies created to manage data retention, continuous aggregates, compression, and other automation policies. For more information about automation policies, see the policies section.

The informational view timescaledb_information.job_errors is defined on top
of the table _timescaledb_internal.job_errors in the internal schema. To
prevent this table from growing too large, a system background job
Error Log Retention Policy [2] is enabled by default,

On Timescale and Managed Service for TimescaleDB, the owner of the error
retention job is tsdbadmin. In an on-premise installation, the owner of the
job is the same as the extension owner.
The owner of the retention job can alter it and delete it.
For example, the owner can change the retention interval like this:
SELECT alter_job(id,config:=jsonb_set(config,'{drop_after}', '"2 weeks"')) FROM _timescaledb_config.bgw_job WHERE id = 2;
