LEFT JOIN not generating `Null*` types with table aliases

[fr3fou]

Version

1.15.0

What happened?

sqlc generates incorrect code when using table aliases inside left joins.
#1491 was supposed to fix it, but I'm still able to reproduce it.
The StripeID field should be of type sql.NullString but it isn't.

Relevant log output

No response

Database schema

CREATE TABLE users (
	user_id uuid primary key  
);

CREATE TABLE user_stripe_customers
(
    user_id   uuid NOT NULL,
    stripe_id TEXT NOT NULL,
    UNIQUE (user_id, stripe_id)
);
ALTER TABLE user_stripe_customers
    ADD FOREIGN KEY (user_id) REFERENCES users (user_id) ON UPDATE CASCADE ON DELETE CASCADE;

SQL queries

-- name: GetStripeUserByUserID :one
SELECT stripe_id, users.user_id
FROM users
         LEFT JOIN user_stripe_customers ON users.user_id = user_stripe_customers.user_id
WHERE users.user_id = @user_id;


-- name: GetStripeUserByUserIDBroken :one
SELECT stripe_id, u.user_id
FROM users u
         LEFT JOIN user_stripe_customers usu ON u.user_id = usu.user_id
WHERE u.user_id = @user_id;

I also found a case where when I left joined table a to b, the generated model for the b columns were not following the types of actual schema model b.
For instance ID for table b is NOT NULL, but the select query a., b. makes all of the b.* results become nullable.

nevermind, I'm dumb, left join implies right side is nullable duh

nevermind actually, it does this for all joins.

I found that sqlc doesn't consider primary key to be NOT NULL. I had to explicitly put it.
