Resolution: Done
Priority: Major
Fix Version/s: 10.0, 9.3.4
Affects Version/s: None
Component/s: Query Engine

Steps to Reproduce:
Hide

Have a table with a column of type timestamp such as:

CREATE TABLE test_z (a timestamp); INSERT INTO test_z (a) VALUES (now());

Add pg as datasource in teiid

Execute both queries and check the query plan:

SELECT FORMATTIMESTAMP(a, 'yyyy') FROM ds_pg.test_z; SELECT formattimestamp(a, 'yyyy') FROM ds_pg.test_z;

FORMATTIMESTAMP (uppercase) is NOT pushed to postgres but formattimestamp (lowercase) is correctly pushed.
