What pg version is this, and can you run the query directly using psql
and have it throw the same error? What do
select * from pg_class where oid = '1152770777'
and
select * from pg_attribute where attrelid = '1152770777'
show? If the latter fails to show an entry for attnum=1, does it
magically appear if you do
SET enable_indexscan=off;
SET enable_bitmapscan=off;
prior to running the query?
