Patchset-v60 implements: * renamed initial_consistent_point to two_phase_at and set it when a stream is started with two_phase on or slot is created with two_phase on. * replication slots are created with two_phase off on start. * start stream with two_phase on only after all tables are in READY state. * Initially the two_phase parameter of the subscription defaults to PENDING and is only enabled once all tables are in READY state. * restrict REFRESH PUBLICATION with copy = true on subscriptions with two_phase enabled. * documentation updates Pending work: * add documentation for START REPLICATION syntax change. regards, Ajin Cherian Fujitsu Australia
