Should the version of pydantic be pinned?

Question about pandera

Hi, if I am not mistaken, pandera requires the installation of pydantic, here but does not ping any version. This leads to some issues if no other package imposes pydantic version to be strictly below version 2 as pandera would currently install pydantic version 2.

For example, it broke our CI this morning when used in pre-commit like the following

repos:
  - repo: https://github.com/pre-commit/mirrors-mypy
    rev: v1.4.1
    hooks:
      - id: mypy
        additional_dependencies:
          - pandera[mypy]==0.13.4

and took us a while to understand the issue (and fix it by adding the version of pydantic in the pre-commit file). Do you think it would be worth pinging the pydantic version to stay below 2?

Thanks in advance,
F.

I made this PR: #1253 that adds provisional support for pydantic, i.e. all the existing unit tests pass with the existing pydantic syntax. There're probably going to more bugs/issues once folks veer off the tested path, but we can tackle those as they come. Will release this as part of 0.16.0.

In the mean time, I'll make a patch release 0.15.2 that pins pydantic so it doesn't continue breaking people's CI.
