using pg_dump to dump only a schema?

hi there,

i'm wondering, if i can use pg_dump to move only one schema of a db from
the one server, intoan other schema on the other server?

for example:

Server A:
Database: xyz_test
Schema: 123

Server B:
Database: xyz_prod
Schema: 999

The tablenames and so on are equal. and i wan't to transfer the data
with it. is it possible? and how? today i played a little bit with it,
but could not find a proper way with it. the description in the docu
didn't helped me either. any solution anyone?

thanx in advance!

bye,
thomas
