Original query:

 create table articles 
(
  id bigint generated always as identity primary key,
  title text NOT NULL,
  content jsonb NOT NULL,
  author_id bigint NOT NULL,
  created timestamptz NOT NULL default now(),
  edited timestamptz NOT NULL default now(),
  FOREIGN KEY (author_id) REFERENCES users(id) ON UPDATE CASCADE ON DELETE CASCADE
 );

Prettified:

CREATE TABLE "articles" (id bigint  PRIMARY KEY, title text NOT NULL, content jsonb NOT NULL, author_id bigint NOT NULL, created timestamptz NOT NULL DEFAULT now(), edited timestamptz NOT NULL DEFAULT now(), FOREIGN KEY ("author_id") REFERENCES "users" ("id"))
