Subject: [PATCH v2] Add CHECK_FOR_INTERRUPTS in logical decoding's processing
 changes loop.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a CHECK_FOR_INTERRUPTS() call in the main loop of processing
logical changes to make the logical decoding responsive to cancellations,
especially while the plugin skipping all changes.

Per bug #17580 reproted from 巨鲸 and Andrey Borodin. Backpatch to all
supported branches.
