The cursor name (portal name) is global to the session, and for a bound
cursor it defaults to the name of the cursor variable:
40.7.3.5. Returning Cursors
[...]
Note: A bound cursor variable is initialized to the string value
representing its name, so that the portal name is the same as the
cursor variable name, unless the programmer overrides it by assignment
before opening the cursor. But an unbound cursor variable defaults to
the null value initially, so it will receive an
automatically-generated unique name, unless overridden.
It's a bit ugly, but you can do
declare
cur for select 1;
begin
cur := null; -- force a unique generated portal name
open cur;
//...
