As reported by Michael [1], there is one test failure related to this
commit. The failure is as below:
# Failed test 'transaction is prepared on subscriber'
# at t/021_twophase.pl line 324.
# got: '1'
# expected: '2'
# Looks like you failed 1 test of 24.
[12:14:02] t/021_twophase.pl ..................
Dubious, test returned 1 (wstat 256, 0x100)

I think I know what's going wrong here. The corresponding test is:
# Now do a prepare on publisher and check that it IS replicated
$node_publisher->safe_psql('postgres', "
BEGIN;
INSERT INTO tab_copy VALUES (99);
PREPARE TRANSACTION 'mygid';");
$node_publisher->wait_for_catchup($appname_copy);
# Check that the transaction has been prepared on the subscriber,
there will be 2
# prepared transactions for the 2 subscriptions.
$result = $node_subscriber->safe_psql('postgres', "SELECT count(*)
FROM pg_prepared_xacts;");
is($result, qq(2), 'transaction is prepared on subscriber');
Here, the test is expecting 2 prepared transactions corresponding to
two subscriptions but it waits for just one subscription via
appname_copy. It should wait for the second subscription using
$appname as well.
What do you think?
