Might be worth bumping the min version to https://github.com/googleapis/python-bigquery-pandas/releases/tag/v0.18.1 so users also don't get bit by pyarrow being pinned Ugh 0.18.1 isn't on conda-forge.

Is it fine to just go directly to 0.19.x? > Ugh 0.18.1 isn't on conda-forge.

Yeah that should be fine A few more places need bumping otherwise looks good Not entirely making sense of the error, but looks like there is a conflict between pyarrow dependencies
(aws-sdk-cpp) and google-bigquery dependencies(grpcio) fighting over openssl 1 and openssl 3.

I think what needs to happen is that we need to bump pyarrow from 7 to something newer. 

PDEP-10 stops this from happening for 2.1, but maybe we can bump as soon as 2.2?
There seems to be no support plan in that PDEP, stopping us from bumping pyarrow as we please.
