Postgrex Version

Current behavior

https://github.com/elixir-ecto/postgrex/blob/master/CHANGELOG.md for v0.19.3 (2024-11-12) says it includes "Call disconnect on protocol when reconnecting in Postgrex.SimpleConnection". But I believe that fix is this commit from 2024-11-28, after the release date.

That fix turns out to be important for us - we had a tough to find bug that ended up being due to Postgrex.SimpleConnection not re-establishing a connection after one silently stopped responding. We're pointing to main for now but a new release with that commit would be helpful.

Expected behavior

The latest release should include the bugfix
