That would be tricky because the list of subscription OIDs can be longer than the workers. Can't we set a boolean variable (check_immediate or something like that) in LogicalRepCtxStruct and use that to traverse the subscriptions? So, when any worker will restart because of a parameter change, we can set the variable and send a signal to the launcher. The launcher can then check this variable to decide whether to start the missing workers for enabled subscriptions. -- With Regards, Amit Kapila.
