Description

opened on Sep 8, 2022

Release 3.0.0 introduced the use of nullable Int64 and boolean dtypes (pandas extension dtypes) (#786)

However the pandas extension dtypes are not widely supported across the pandas api. This might lead to issues using numba in pandas operations.

Please see my bug report in the pandas project for example:
pandas-dev/pandas#46867

I would propose to introduce an optional switch to pre-3.0.0 behaviour.
