Foreign Key, is this method deprecated?

import {
  foreignKey,
  index,
  pgTable,
  primaryKey,
  text,
  timestamp,
  uuid,
} from "drizzle-orm/pg-core";

export const profiles = pgTable("profiles", {
  id: uuid("id").primaryKey().notNull(),
  username: text("username").notNull().unique(),
  createAt: timestamp("created_at").defaultNow().notNull(),
});

export const posts = pgTable(
  "posts",

      .notNull()
      .references(() => profiles.id),

    createAt: timestamp("created_at").defaultNow().notNull(),
