Any chance you could write a tap test exercising a few of these cases?
E.g. things like:
- create a few slots, drop one of them, shut down, start up, verify
stats are still sane
- create a few slots, shut down, manually remove a slot, lower
max_replication_slots, start up
IMO, independent of the shutdown / startup issue, it'd be worth writing
a patch tracking the bytes sent independently of the slot stats storage
issues. That would also make the testing for the above cheaper...
