it looks like you are hitting pretty much the same problem as I:

The only major difference, you are restoring from the backup, while in
my case the host running replica has crashed.
Also in my case, the primary was already running 9.6.10.
In my case, it also panics during "Btree/DELETE: XYZ items" and page
number of relation is insanely huge.
