Browse Source 
AUTHORIZATION clause to specify the desired owner.  This allows a
superuser to restore schemas owned by users without CREATE-SCHEMA
permissions (ie, schemas originally created by a superuser using
AUTHORIZATION).  --no-owner can be specified to suppress the
AUTHORIZATION clause if need be.
