Re: PreparedStatement error for date parameter with overlaps

That's not going to work, because the syntax
    date 'something'
only works for literal constants, and a ? marker is not a literal constant.
You could try
    ?::date
or
    CAST(? AS date)
if you prefer to avoid Postgres-specific syntax.  Even better, don't use
setString --- that's really only meant for parameters that are of string
datatypes.
