findepi opened a new issue, #14461:
URL: https://github.com/apache/datafusion/issues/14461

   https://github.com/apache/datafusion/pull/13523 fixed some queries with 
unnest in subquery without adding support for unnest decorelation ([which is 
possible](https://github.com/trinodb/trino/pulls?q=is%3Apr+decorrelate+unnest+is%3Amerged))
 by changing the check function not to fail on unnest nodes.
   It would be better, however, if the check function didn't check uncorrelated 
plan nodes at all. An uncorrelated part of the plan is a unit that doesn't need 
to be analyzed.
