The query callback can only be called once (and if it weren’t, we wouldn’t want to silently ignore that):

It will cause this error, as the connection also gets terminated, and the callback will be executed again.
Message: 'Connection terminated' == 'Query parameter value cannot be an invalid date.'
AssertionError [ERR_ASSERTION]: 'Connection terminated' == 'Query parameter value cannot be an invalid date.

PR for Issue #3318
Issue Description:
Currently, new Date(undefined) (an invalid date) is serialized as "0NaN-NaN-NaNTNaN:NaN:NaN.NaN+NaN:NaN". It should fail early with a JS error instead of being passed to the database.
