12.4. Both of those queries return no rows, with and without those options set.
We do do some nightly processing of data during the same window, in which views are re-materialized: would that cause this issue? No non-temporary tables are dropped or re-created, though.

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?
