I am not seeing that.

For:

pg_dump -d test -U postgres -s --create --schema=other_sch --schema=public

In the output I get:


[...]

CREATE SCHEMA other_sch;


ALTER SCHEMA other_sch OWNER TO postgres;

--
-- Name: public; Type: SCHEMA; Schema: -; Owner: pg_database_owner
--

CREATE SCHEMA public;


ALTER SCHEMA public OWNER TO pg_database_owner;

[...]

What is the complete command you are using for the pg_dump?

What Postgres version(s) are you using?
