pg_dump without setting search_path

When I use pg_dump to export schema from a database, it adds the following line at the beginning:

SELECT pg_catalog.set_config('search_path', '', false);

Is it possible set an option where pg_dump will not add this line? 

It is causing issues later when I try to execute other SQL commands, without the schema qualifier.

This is the pg_dump command I am using right now:

pg_dump -O -x -h <db-host> -p <db-port> -U <db-user> -d <db-name> --schema public --schema-only > public-schema.sql
