Yes, that approach is better. Also this is not required after checking
using pg_subscription:
+# Prepare a transaction on the publisher
+$node_p->safe_psql(
+ $db1, qq[
+ BEGIN;
+ INSERT INTO tbl1 SELECT generate_series(1, 10);
+ PREPARE TRANSACTION 'test_prepare';
+]);
+
# Start subscriber
$node_s->start;
+# Verify that the prepared transaction is replicated to the subscriber
+my $count_prepared_s =
+ $node_s->safe_psql($db1, "SELECT count(*) FROM pg_prepared_xacts;");
+
+is($count_prepared_s, qq(1), 'Prepared transaction replicated to subscriber');
