Imagine I have these schemas: ```ts // users table export const users = pgTable("users", { id: uuid("id").primaryKey().defaultRandom(), name: text("name"), }); // projects table export const projects = pgTable("projects", { id: uuid("id").primaryKey().defaultRandom(), userId: uuid("user_id").references(() => users.id), title: text("title"), }); ``` How can I select all users, and their related projects?
