django-tenants postgis with multischema

Question

How can i install postgis extension for 2 shema? shema_1 and shema_2, my commands:

CREATE SCHEMA IF NOT EXISTS shema_1 AUTHORIZATION admin;
CREATE SCHEMA IF NOT EXISTS shema_2 AUTHORIZATION admin;
SET search_path = shema_1, shema_2, public;
CREATE EXTENSION IF NOT EXISTS postgis;

Its install only for shema_1, and command
CREATE EXTENSION IF NOT EXISTS postgis WITH SCHEMA schema_2;
says postgis already exists.
In settings.py set ORIGINAL_BACKEND = "django.contrib.gis.db.backends.postgis"
