The restore command is:
pg_restore.exe --verbose --single-transaction -h <ip> -p <port> -d
<dbname> -U postgres <path-to-pgdump-file>
But how will I avoid the issue if the command `SELECT
pg_catalog.set_config('search_path', '', false);` is part of the pgdump
file? Wouldn't that override the config file setting during the restore
process?

In my case I use a separate Postgres cluster for each database and the
roles, absent of any successful hacking, are all limited to trusted
users, so the risk mentioned in the CVE is non-existent and it would be
great if there was an option to turn off that "feature".
Thanks,
