OK I can see why the gate passes, the error is exposed only by
Alembic 0.8, because the Column() in the remove operation has no
Table associated with it. <br>
<br>
But the code is still wrong and should be fixed. <br>

and here it is failing tests on my local env, as it does on
my CI, as would be expected, there's a lot more if I keep it
running:<br>

However, utterly weirdly, all those tests *pass* with the
same versions of everything in the gate:<br>
<br>

I have no idea why this is. This might be on the oslo.db
side within the test_migrations logic, not really sure.
If someone feels like digging in, that would be great.<br>
<br>
The failure occurs with both Alembic 0.7.7 and Alembic 0.8
as yet unreleased. I have a feeling that releasing Alembic
0.8 may or may not bump this failure to be more widespread,
just because of its apparent heisenbuggy nature, and I'm
really hoping to release 0.8 next week. It was supposed to
be this week but I got sidetracked.<br>
