[HACKERS] pg_dump problems against 7.0

[Christopher Kings-Lynne]

I noticed that the function to get max builtin OID for 7.0 does this:

template1=> SELECT oid from pg_database where datname = 'template1';
  oid
-------
 17216
(1 row)
However, that is incorrect:

template1=> select oid,relname from pg_class where oid > 17216;
  oid  |  relname
-------+------------
 17408 | pg_indexes
 17280 | pg_user
 17312 | pg_rules
 17344 | pg_views
 17376 | pg_tables
(5 rows)
Which results in all the system views being dumped.  Attached is a 
patch.  Please tell me if it's OK.
