Ah.. I think I got your point. I thought that the message
"terminating process to release replication slot X" is showing the
cause for process termination but actually it doesn't mention the
reason for releasing replication slot. For persistent slots the
following message "invalidating slot" does that but that message is
absent for temporary slots. However, in that sense, the root reason
is not clearly stated in any case.
So I'm going to propose something like the following.
LOG: terminating process nnnnn to release replication slot "slot"
+ DETAIL: The WAL files retained by the slot is going to exceed max_slot_wal_keep_size.
Thanks!
