    Oops...I must be using that wrong...I'm getting:

NOTICE:  Message from PostgreSQL backend: The Postmaster has informed me
     that some other backend died abnormally and possibly corrupted
     shared memory.  I have rolled back the current transaction and am
     going to terminate your database system connection and exit.
     Please reconnect to the database system and repeat your query.


    relname is of type NameData ... NameData is a struct, so shouldn't
it be:

    Relation->rd_rel->relname->data

    But, NameData only has one component, data...why make it a struct?
