You still haven't stated why you think it is blocked?
Ouput from iotop:
3990 be/4 postgres 0.00 B/s 0.00 B/s 0.00 % 0.00 % postgres:
postgres flip [local] CREATE INDEX
The process isn't reading or writing anything for many hours, but it's
using almost 90% of CPU.
How long has it been taking?

More than 50 hours.
What is your maintenance_work_mem set to?
maintenance_work_mem = 352MB
