Inaccurate Type Narrowing when using `.selectAll` on multiple tables

[hughgardiner]

I'm curious how feasible it is to have the typescript response types accurately reflect the correct types based on the order of .selectAll('table') statements.

For example:

const rows = await db
  .selectFrom("person")
  .leftJoin("pet", "pet.person_id", "person.person_id")
  .selectAll("person")
  .selectAll("pet")
  .execute();

Because this generates

select person.*, pet.*

the pet fields take priority in the output, which makes person_id possibly null given the fact that we are performing a left join

However, the generated response type says person_id is not nullable. if you reverse the order, the expected outcome of person_id being non-nullable is accurate as the `person.person_id field will always be present

Updated Playground with same name person_id columns
