Indeed, but like I said in my initial e-mail::
I know you can use DECLARE, but I believe that this inhibits the driver from being able to select the transfer
formatfor individual columns; it's all binary or it's all text. Also, I don't think I can DECLARE against a
preparedstatement, save restating the
query, no?
Also, the latter has other problems wrt statement parameters. I guess
you
could prepare(protocol level) the DECLARE, but that seems like a gross
workaround as it defeats the purpose of prepared statements by forcing
you
to create a new statement for each cursor that you plan to open. Of
course,
unless you can close the existing one before opening the next one.
