Hi,
I got the $SUBJECT error in a logical replication setup. Both versions
are 10.3. I remembered that some bugs in the piece of code around this
error were fixed in 9.6 but it seems not all of them. Unfortunately I
don't have a test case. All DEBUG3 messages from an unsuccessful
replication attempt are attached. The last few messages from the
logical replication role are:
