I'm updating a table that has a field which is datatype 'date' this
field maybe filled out or not before update. If the field is left blank
I get an error, if I test to see if the field is empty and if it is, set
the value to 0001/01/01 then postgres will accept this. I would rather
the field remained empty but setting the field to 'null' is not accepted
by postgres. Im using php to test and set the value.
