I have noticed that the failure to replicate correctly can be avoided by
putting a wait state of (on my machine) at least 3 seconds between the
setting up of the subscription and the start of pgbench. See the bash
program I attached in my previous mail. The bug can be avoided by a
'sleep 5' just before the start of the actual pgbench run.

So it seems this bug is due to some timing error in your patch (or
possibly in logical replication itself).
