Thanks, the patch worked in my environment. We have made a similar fix
earlier at commit "def0ce3370689b939c6d7a3c3eb824d69989ef6e".
Can you add one comment to say something like:
# Make sure pg_hba.conf is set up to allow connections from regress_seq_repl.
# This is only needed on Windows machines that don't use UNIX sockets.
+$node_publisher->init(
+ allows_streaming => 'logical',
+ auth_extra => [ '--create-role' => 'regress_seq_repl' ]);
