Yeah, this is not a bug.

I'm not sure that it's a sane feature request either.  pg_dump scripts are
not designed to deal with concurrent modifications to the target database
during restore, and I doubt that we want to invest effort in making them
proof against such situations.  Even if you only consider read-only
concurrent accesses, what client is going to be pleased with seeing a
half-restored database?  So I don't quite follow what is the use-case
for doing DROP DATABASE FORCE here.  Realistically you need a stronger
defense against concurrent users than that would offer.

            regards, tom lane
