pgTableCreator on creating constraints

export const contacts = createTable(
  "contacts",
  {
    email: varchar("email")
      //
      .primaryKey(),

    first_name: varchar("first_name"),
    last_name: varchar("last_name"),

    phone_number: varchar("phone_number")
      //
      .unique(),

    created_at: timestamp("created_at", { withTimezone: true })
      //
      .default(sql`CURRENT_TIMESTAMP`)
      .notNull(),
  },
  (table) => ({
    phone_number: check("phone_number_check", sql`LENGTH(${table.phone_number}) >= 10`),
  }),
);

export const users = pgTable(
  "users",
  {
    id: uuid().defaultRandom().primaryKey(),
    username: text().notNull(),
    age: integer(),
  },
  (table) => [
    check("age_check1", sql`${table.age} > 21`),
  ]
);
