Обсуждение: Proposed TODO: fetch->INT8

I was browsing the TODO list and I noticed the todo to bump limit/offset
to int8.  IMO, the flavors of fetch that take a numeric parameter need
this as well.

FWIW, trying to pass integer > 2^31 to fetch gives a syntax error, which
is clearly wrong.

Is there a practical use for retrieving > 2^31 records at once?

(this is a serious question, I'm not arguing that it should cause a
syntax error)

No, but don't forget about relative positioning:
fetch relative c from huge_cursor;

Could make a reasonable case for that.
