Sorry, I know that I proposed this, but now I am getting a compilation
error here:

tarantool/src/box/sql/select.c:1850:33: error: comparison of integers of different signs: 'uint32_t' (aka 'unsigned int') and 'int' [-Werror,-Wsign-compare]
                                    space->sequence_fieldno == iCol)

I don't know why was not it raised earlier.

I've pushed my review fix on top of this commit. See it below
and on the branch.
