PreparedStatement.toString() isn't guaranteed to give you the query as
executed (or even a syntactically correct query!), it just substitutes
parameter values into the query string to give you something that
might be more useful for debugging than the default Object.toString()
implementation.
If you wanted to get the equivalent query in psql, you should take
your query string and replace ? with $1, $2, etc, then use
PREPARE/EXECUTE. That's much closer to how the JDBC driver actually
executes queries; the driver does *not* just substitute values into
the query string.
