Thank you David, so I am on the right track.

Hm, lsyscache.c says for get_rel_name():
* NOTE: since relation name is not unique, be wary of code that uses this
* for anything except preparing error messages.
How do I get the schema name too, then?
Call get_rel_namespace() and then get_rel_name() again with the Oid that was returned?
