I have the following condition a select statement:
WHERE "datetime" > '2019-03-31 23:59:59'
datetime is a character field with data in the format YYYY-MM-DD HH:MM:SS. However it returns any line where the
datetimefield begins with 2019. I suspect that I should be using timestamp values, but I can't figure out how to cast
thedatetime field value to a timestamp.

SELECT to_date('20170103','YYYYMMDD');
