Apparently I am. libpq docs claim that "You can query the system table
pg_class to determine exactly which table is referenced." for PQftable.
I query pg_class and the only column that looks remotely like a unique
oid is relfilenode. The other thing is that it works most of the time
and starts to work again when I dump and restore.
Thanks
