Extend the replication command CREATE_REPLICATION_SLOT to support the TWO_PHASE option. This will allow decoding commands like PREPARE TRANSACTION, COMMIT PREPARED and ROLLBACK PREPARED for slots created with this option. The decoding of the transaction happens at prepare command. This patch also adds support of two-phase in pg_recvlogical via a new option --two-phase. This option will also be used by future patches that allow streaming of transactions at prepare time for built-in logical replication. With this, the out-of-core logical replication solutions can enable replication of two-phase transactions via replication protocol.
