Description
I have a translator that does not support aggregates or grouping. I am using a view to try to normalize data from several sources. I am duplicating some of the fields as an approximation. I have existing software that is querying with GROUP BY, and sometimes this happens.
This query works fine in 8.6:
select identifier from foo.items group by identifier, identifier;
In 8.7 this happens:
