Also, we should match Cloud SQL and drop Python 3.8. See GoogleCloudPlatform/cloud-sql-python-connector#1176.

Python 3.13 was added in asyncpg 0.30.0 so once #375 is merged this should be good to go

After #375 is merged, do we need to modify setup.py so that its asyncpg version is >= 0.30.0?: https://github.com/GoogleCloudPlatform/alloydb-python-connector/blob/main/setup.py#L80

That is a good question and one that I have been thinking about. Since we don't pin to a specific version, if the asyncpg package is not already installed in the environment pip will download the latest version by default, so fresh Python 3.13 installs would get 0.30.0 automatically with our current setup.

However since we are planning to document native asyncpg pool support with the Connector #382 which was also added in v0.30.0 then I think between the two of these it is worth pinning to >=0.30.0 in setup.py.

For Cloud SQL I am going to pin to v0.30.0 as part of adding native connection pool examples.

[rhatgadkar-goog]

I agree with you. I'll also pin to v0.30.0 as part of adding native connection pool examples in #382

Looks like this was linked to the dropping of Python 3.8 PR by accident
