[3.0]: New columns not being added to tables

[Oldiesmann]

Basic Information

When running upgrade.php, you will run into an error when you hit the db_fetch call on line 1933 of upgrade.php because we're trying to pull id_event and uid from the calendar table but no uid column has been added at that point

Steps to reproduce

1. Try upgrading a forum on PostgreSQL (this should affect MySQL as well but #8197 is preventing it from getting that far at that point)
2. Blank screen after backup because there is no "uid" column in the calendar table

Expected result

Expect upgrade to run smoothly

Actual result

Fatal error: Uncaught TypeError: SMF\\Db\\APIs\\PostgreSQL::fetch_assoc(): Argument #1 ($result) must be of type object, false given, called in /.../upgrade.php on line 1933

I should also note that I didn't run into this while working to debug the previous upgrade issues because I had already manually added the missing columns in phpMyAdmin.
