I have several tables, and I need to create a matching _hist table for each one. For example if I have:

CREATE TABLE public.test (
    first       text,
    middle      text,
    "last"      text,
    "timestamp" timestamp without time zone NOT NULL default now()
);

I would like to create:

CREATE TABLE public.test_hist (
    "action"    text,
    "user"      text,
    first       text,
    middle      text,
    "last"      text,
    "timestamp" timestamp without time zone NOT NULL default now()
);

I'm in the initial phase of the project I'm working on, and requirements keep changing.

As I run the changed script that drops and re-creates tables, I would like for _hist tables to somehow get automatically generated, so I don't need to make the same change in two places.

Is it possible to do that with SQL at the end of my table creation script?

I have postgreSQL 10.

Or should I do it in python?
