In my understanding, within a single instance, no two proclists can
simultaneously share the same waitlink member of PGPROC.
On the other hand, a publisher uses two condition variables for slots
and WAL waiting, which work on the same PGPROC member cvWaitLink. I
suspect this issue arises from the configuration. However, although it
is unlikly related to this specific issue, a similar problem can arise
in instances that function both as logical publisher and physical
primary.
Regardless of this issue, I think we should provide separate waitlink
members for condition variables that can possibly be used
simultaneously.
regards.
