   So maybe we should fix it for this driver only + add the startup code to fix it in scheduler + workers waiting (I guess they also can change the state) to run a query fixing it before they start guarded by some flag in the DB set by the migration ('needs state fixing' ) and reset after scheduler fix is run ?  This is a one-time event only after migration.
