There was a problem hiding this comment.
This path does not make sense anymore (you can't call a workflow in "non recovery mode")

This PR simplifies the logic for putting a workflow in the dead letter queue. Specifically, it changes the meaning of the
recovery_attemptcolumn in thedbos.workflow_statustable toattempts*.The default of the column is now 1.
update_workflow_statusjust verifies that (number of attempts) <= max_retries before placing a workflow in the DLQ.[*] This PR does not change the column name, to facilitate backward compatibility.
