Restoring db dump is failing

[svedbg]

When trying to restore the db_scripts/create_empty_db.sql in postgres it's failing with following error:

[utmadmin@castrac7vm db_scripts]$ /usr/pgsql-11/bin/pg_restore -U utmadmin -d utm_dev -1 /home/utmadmin/project/dronfiesuss/db_scripts/create_empty_db.sql 
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 10; 2615 17824 SCHEMA topology postgres
pg_restore: [archiver (db)] could not execute query: ERROR:  must be member of role "postgres"
    Command was: ALTER SCHEMA topology OWNER TO postgres;

Why topology needs postgres?
