That's not the point. I want to prepare a query, like
"prepare myplan(bigint) as select * from adresses where id=$1"
and then
"declare mycurs cursor as execute myplan(47110815)"

That's not possible, as I have to put the source query
behind the cursor declaration.
I WOULD understand when declare failed on prepared
update, delete or insert statements, kind of at least.
But no prepared queries at all?
