Yes, that was the pending item.

There are API related comments.
01.
I think the two-phase should be off by default. Because default value for CREATE
SUBSCRIPTION command is off, and your patch breaks pre-existing style.
02.
API style should be changed: no need to require the argument. I think it is enough
to provide "enable-twophase" and "T" option which specify the two_phase to true.
Best regards,
