Just be aware that a schema only dump has the following restriction:

http://www.postgresql.org/docs/9.2/interactive/app-pgdump.html

-n schema
--schema=schema

Note: When -n is specified, pg_dump makes no attempt to dump any other
database objects that the selected schema(s) might depend upon.
Therefore, there is no guarantee that the results of a specific-schema
dump can be successfully restored by themselves into a clean database.
