Hi,
I noticed this behavior on recent release of PG database. It will be helpful to users, if this behavior is looked into. 

When executed below SQL, got unintended output when i expected it to throw error " not a valid month "

SQL executed:
select to_date('20171231','YYYYDDMM')

result:
2019-07-17


Thank you, Naidu
