Another idea is to teach Valgrind that whenever a backend reduces its

That should be fairly straightforward to implement.

I can see two possible fixes: one to correct the assumptions in the

While the CLOBBER_FREED_MEMORY hack does a fairly good job of catching
stale pointers to already-freed memory, commit fd496129d160950e exhibits

Right. You have to be careful to make sure the standby really did fully
