Thread: pgsql: Make GIN's cleanup pending list process interruptable

Make GIN's cleanup pending list process interruptable

Cleanup process could be called by ordinary insert/update and could take a lot
of time. Add vacuum_delay_point() to make this process interruptable. Under
vacuum this call will also throttle a vacuum process to decrease system load,
called from insert/update it will not throttle, and that reduces a latency.

Backpatch for all supported branches.
