It'll fail, yes, because pg_dump by itself doesn't dump CREATE USER
commands (since users are external to any individual database).
However, it hardly seems "silent" to me.  I see complaints like these:

pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 1851; 1262 116736 DATABASE mydb dbowner
pg_restore: [archiver (db)] could not execute query: ERROR:  role "dbowner" does not exist
    Command was: ALTER DATABASE mydb OWNER TO dbowner;

pg_restore: [archiver (db)] Error from TOC entry 161; 1259 116737 TABLE mytable dbowner
pg_restore: [archiver (db)] could not execute query: ERROR:  role "dbowner" does not exist
    Command was: ALTER TABLE public.mytable OWNER TO dbowner;

WARNING: errors ignored on restore: 2

Possibly you want to use the --exit-on-error option?
