Yeah, you need to first deny access rights to all users that aren't
the one doing the loading, then kick off all the users that are
already connected. To remove the rights of anyone else to connect,
the easiest way is to edit pg_hba.conf / have a special pg_hba.conf to
copy into place, then reload the db. After that, from a shell script
or something, you need to kill the backends that are still connected.
