It is aborted as soon as the server realizes that the client is gone, which may
take a while (see the keepalive parameters and "client_connection_check_interval").

The answer is the same.
Note that if CREATE INDEX CONCURRENTLY is interrupted, you are left with an
INVALID index that you have to delete later.

It blocks until the index has been created.
Do you want to propose a patch?
