Generally speaking looks great 👌🏻

Just a few questions.

I will look into the impala/druid failures since they seem to be consistent (but are passing on upstream/the-epic-split)

Oooh, I hadn't really thought about this but I suspect we should probably apply this transform in general to backends whose quoted value is True.

Anyway, follow-up fodder.

We have this method in many of the backends. Nothing to do here except note for a follow up to perhaps generalize a bit.

I don't know if there's a better way to do this, but the regular mapping in Oracle.Generator.TYPE_MAPPING didn't expose the scale parameter

At some point we should upstream the bug report to sqlglot

Ok, I have this down to 3 failing tests locally. I've been staring at it for long enough that I'm not going to get anywhere else today. I'll pick it back up on Monday.

fix(tests): filter None from tuples of raises
78cab6d 
In ibis/backends/tests/error.py we define the fallback exception types
as `None` if they cannot be imported (because the parent package isn't
installed).

This can lead to passing a tuple of possible exceptions that looks like

```
raises=(ImpalaHiveServer2Error, None, OracleDatabaseError)
```

If this gets passed without filteing, then you can end up with a gnarly
internal pytest error.

To avoid this, we filter out any `None` we find in `raises` while
handling the custom pytest markers.
