I've made implementations for
DatabaseMetaData.getImportedKeys,
DatabaseMetaData.getExportedKeys, and
DatabaseMetaData.getCrossReference.
I don't have a .patch file, because I'm new to open-sourcing and don't know how to make one, but I have attatched the relevant code segment.
Please tell me if there's something else I need to do to have the patch applied.
Thanks,
Russell
