Yeah, and by the time it happens you'll have gotten bored and found
something else to do.  With no support in the system for random access
to a cursor result, this is just about as useless as the FETCH case.

In any case I agree with Alvaro's comment: the way to support int8 in
a FETCH/MOVE command is not to try to convert the entire rest of the
grammar to int8 instead of int4 as its native datatype.
