Re: [JDBC] JDBC and Binary protocol error, for some statements

Thank you, but I think about this last night. Opening unnecessary portals
isn't good idea, similarly sending 2nd describe when statement was
prepared. Currently JDBC drivers doesn't make this. I think better will be
to store what format we had requested on stack, and then coerce those
formats when results are handled.

Kind regards,
