Both databases run on Google Compute Engine VMs with Debian 9, both PGs are "PostgreSQL 11.1 (Debian 11.1-1.pgdg90+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516, 64-bit"
I did several tests with setting logical replication from master to replica always dropping everything and setting it "from scratch" again with exactly the same bash script running plpgsql commands in psql and only during one of these tests got this error. And now I cannot repeat it.
Not sure if it can be important in this context but database processes several thousands of inserts each minute, most of them just 1 record in separate transaction - those are metric data from web widgets.

That's definitely a bug. Are you on the latest minor release of whichever release series you're using? (And which one is that?) If it is latest, please see if you can make a self-contained test case that triggers this.
