Greenplum DB - BQT correlated subquery failures

Testing Greenplum DB against Teiid 7.6.0 Final. Greenplum DB is returning the following on 59 BQT queries: Remote org.postgresql.util.PSQLException: ERROR: Greenplum Database does not yet support that query. Detail: The query contains a correlated subquery. I am using the postgresql Translator.

A couple example queries are listed below:

SELECT INTKEY, STRINGNUM FROM BQT1.SmallA AS A WHERE NOT (EXISTS (SELECT STRINGNUM FROM BQT1.SmallA AS B WHERE B.INTKEY = A.INTKEY))

SELECT INTKEY, STRINGKEY FROM BQT1.SMALLA AS A WHERE STRINGKEY = (SELECT MASTRINGKEY) FROM BQT1.SMALLA AS B WHERE A.INTKEY = B.INTKEY) ORDER BY INTKEY, STRINGKEY
