Should this exist in the main repo now that the bigquery backend has been ported back there?

[cpcloud]

This test does exist there, and master is passing so I don't think it's actually a problem.

[tswast]

I think you're right that this has been fixed in the main ibis repo. I've still got some projects using this package on ibis 3.x, so I'd like to keep this open to backport a fix if it's possible to do so from the ibis-bigquery package.

[cpcloud]

SGTM!

Re-opening just to double-check if this fix is needed in the ibis 4.x repo.
