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?
