okay, all i get from
select c.relname,a.attname
from pg_class c,pg_attribute a
where a.attrelid=c.oid
AND a.attname LIKE 'table%'
order by attname,relname;
is
relname | attname
------------+------------
pg_indexes | tablename
pg_rules | tablename
pg_tables | tablename
pg_tables | tableowner
cmax, xmin and oid show up, but no tableoid.
is it a 7.1 thing? i'm using 7.0.3...
