Thank you for your update. v65 didn't make any failure during make check-world.

I've written additional tests for alter subscription using refresh
for enabled subscription and two_phase = on.
I wrote those as TAP tests because refresh requires enabled subscription
and to get a subscription enabled, we need to set connect true as well.

TAP tests are for having connection between sub and pub,
and tests in subscription.sql are aligned with connect=false. 

Just in case, I ran 020_twophase.pl with this patch 100 times, based on v65 as well
and didn't cause any failure. Please have a look at the attached patch.


Best Regards,
