Yep, I remember that and fixed that for literals:

tarantool> select 1
---
- metadata:
  - name: '1'
    type: integer
  rows:
  - [1]
…

But failed (simply forgot) to fix that for binding values.
So, juts want to clarify: we never set “UNSIGNED” type for
literals, even if they are in range [2^63, 2^64-1], right?

If so, patch turns out to be pretty simple.
