(2) interrupt VACUUM when it is running.
Another approach is to interrupt the running VACUUM. VACUUM checks
for a smart stop request at normal vacuum delay points, if such a
request is detected, a flag is set to tell VACUUM to stop at a
right
point. VACUUM stops at the end of one full fill-workmem-clean-index
-clean-deadtuple cycle.
What about 2a: when an interrupt is requested, if the heap scan i sin
progress stop it immediately and proceed to index cleanup, rather
than waiting for maintenance_work_mem to fill.
