How can I rename a schema name that was incorrectly named when it was created?

Thanks
and we said..
there are none, the references to it must be hunted down and changed, the schema itself would have to be exported, and imported using "fromuser=bad_name touser=good_name" (and even then, you would be responsible for grants to good_name and public synonyms) the easiest approach would be to change your view on the name of the schema that is, accept it for what it is and go with it.
