@hiro-o918 would you mind to add model example where you do need such requirement ?

@svdimchenko
Thank you for your reaction.
This PR aims to support a model that has a column named by a pre-reserved word like from
A related PR is dbt-labs/dbt-core#7537.

This PR is still in progress because I have not set up an environment for functional tests.
