CTE optional columns

[npapapietro]

PR Info

The definition of Common Table Expressions (CTE) allow for optional column definition, allowing for using the table
name as the identifier for columns.:

-- Should be equal
-- Case 1
WITH "cte" ("id") AS (SELECT "tbl"."id" FROM "tbl")
SELECT "cte"."id" FROM "cte";
-- Case 2
WITH "cte" AS (SELECT "tbl"."id" FROM "tbl")
SELECT "cte"."id" FROM "cte";

Fixes

Currently, the query building will squish the cte name against the AS keyword like:

WITH "cte"AS (Select ...

so I added a simple fix to add a space:

WITH "cte" AS (Select ...

Additionally I added simple unit test to illustrate.
