Vladimir> pgjdbc just passes "unknown type" formatted as full timestamp

Vladimir>That backfires for the case "select ?" when backend has no way to tell what was the "expected bind type"

It might be the case the proper solution is something around

and 

setObject(int parameterIndex, Object x, SQLType targetSqlType,
         int scaleOrLength)

Of course, those methods just throw "not implemented", however setObject(..., SQLType.TIMESTAMP) might be the way.
