Conservation of OIDs.  Assigning an OID to every row of pg_attribute
chews up lots of OIDs, for a table that should never be referenced by
OID --- its primary key is (table OID, attribute number).

Right now this isn't really significant, but if/when we have an option
to suppress OID generation for user tables, I have every intention of
applying it to a bunch of the system tables as well.  pg_attribute is
a prime candidate.
