I have two comments about the TAP portion of ab55d74.

+$node_subscriber->append_conf('postgresql.conf', "log_min_messages = debug1");
+$node_subscriber->reload;
Wouldn't it be better to make sure that the change is effective before
moving on to the end of the test?

+my $logfile = slurp_file($node_subscriber->logfile());
+ok( $logfile =~
+     qr/logical replication did not find row to be updated in replication target relation "tab_full_pk"/,
+   'update target row is missing');
I think that it would be better here to grab the log location before
running the queries that will be matched with the logs, then pass down
the location to slurp_file().
