Hi,
I haven't followed this thread and maybe this instabilty is
known/expected; just thought I'd let you know.
When doing running a pgbench run over logical replication (cascading
down two replicas), I get this segmentation fault.

This error happens somewhat buried away in my test-stuff; I can dig it
out and make it into a repeatable test if you need it. (debian
