> The following valid SQL query:
> {code:sql}
> select "customer_id" as "*" from "customer";
> {code}
> changes slightly semantics when it is parsed, optimized, and transformed back to SQL via {{RelToSqlConverter}}. 
> +Actual+
> {code:sql}
> SELECT "customer_id" AS """*""" FROM "foodmart"."customer";
> {code}
> Note the extra quotes appearing in the {{AS}} clause. Aliasing columns differently is undesirable and can have an impact when this query pattern appears as part of a larger query and there are usages of the alias.
> +Expected+
> {code:sql}
> SELECT "customer_id" AS "*" FROM "foodmart"."customer";
> {code}
