Hi! Thanks for the review. I will do it later separately.

Nikita, could you, please, see the patch?

commit 88a84a138550012a8e8476a33deb09b51d0eccba
Author: Roman Khabibov <roman.habibov@tarantool.org>
Date:   Thu Mar 5 12:48:58 2020 +0300

    sql: unify pattern for column names
   =20
    Name resulting columns generated by an expression or <VALUES>
    construction by the "COLUMN_N" pattern.
   =20
    Closes #3962
   =20
    @TarantoolBot document
    Title: Column naming in SQL
   =20
    Now, every auto generated column is named by the "COLUMN_N"
    pattern, where N is the number of generated column in a query
    (starting  from 1). Auto generated column is a column in a query
    result generated by an expression or a column from <VALUES>
    construction.
   =20
    Examples:
    ```
    box.execute("VALUES(1, 2, 3);")
    ---
    - metadata:
      - name: COLUMN_1
        type: integer
      - name: COLUMN_2
        type: integer
      - name: COLUMN_3
        type: integer
      rows:
      - [1, 2, 3]
    ...
    box.execute("SELECT * FROM (VALUES (1+1, 1+1));")
    ---
    - metadata:
      - name: COLUMN_1
        type: integer
      - name: COLUMN_2
        type: integer
      rows:
      - [2, 2]
    ...
    box.execute("SELECT 1+1, 1+1;")
    ---
    - metadata:
      - name: COLUMN_1
        type: integer
      - name: COLUMN_2
        type: integer
      rows:
      - [2, 2]
    ...
    ```
   =20
    Here, the expression "mycol + 1" generates a new column, so that
    it is the first auto generated resulting column will be named as
    "COLUMN_1".
    ```
    tarantool> CREATE TABLE test (mycol INT PRIMARY KEY);
    ---
    - row_count: 1
    ...
   =20
    tarantool> SELECT mycol, mycol + 1 FROM test;
    ---
    - metadata:
      - name: MYCOL
        type: integer
      - name: COLUMN_1
        type: integer
      rows: []
    ...
    ```
    Note that you can use generated names already within the query,
    e.g. in <ORDER BY> clause.
    ```
    tarantool> SELECT mycol, mycol + 1 FROM test ORDER BY column_1;
    ---
    - metadata:
      - name: MYCOL
        type: integer
      - name: COLUMN_1
        type: integer
      rows: []
    ...
    ```
   =20
    It should also be noted that if you use column names similar to
    the "COLUMN_N" pattern, you can get the same names as a result:
   =20
    ```
    tarantool> CREATE TABLE test (column_1 SCALAR PRIMARY KEY);
    ---
    - row_count: 1
    ...
   =20
    tarantool> INSERT INTO test VALUES(1);
    ---
    - row_count: 1
    ...
   =20
    tarantool> SELECT column_1, column_1 + 1 FROM test;
    ---
    - metadata:
      - name: COLUMN_1
        type: scalar
      - name: COLUMN_1
        type: scalar
      rows:
      - [1, 2]
    ...
    ```
