Checklist

If this is a user-facing code change, like a bugfix or a new feature, please ensure that
you've fulfilled the following conditions (where applicable):

• You've added tests (in tests/) added which would fail without your patch
• You've updated the documentation (in docs/, in case of behavior changes or new
  features)
• You've added a new changelog entry (in docs/versionhistory.rst).

If this is a trivial change, like a typo fix or a code reformatting, then you can ignore
these instructions.

Updating the changelog

If there are no entries after the last release, use **UNRELEASED** as the version.
If, say, your patch fixes issue #999, the entry should look like this:

* Fix big bad boo-boo in the async scheduler (#999 <https://github.com/agronholm/apscheduler/issues/999>_; PR by @yourgithubaccount)

If there's no issue linked, just link to your pull request instead by updating the
changelog after you've created the PR.

Why?

[HK-Mattew]

Why?

Before, when installing the requirements with just the command:
pip install -e .[test]

And then running the tests, all tests related to psycopg were skipped saying that psycopg was not installed.

[HK-Mattew]

Maybe this didn't happen to you because you already had the requirements installed on your system before installing psycopg.

Then why is it not happening in the CI either? https://github.com/agronholm/apscheduler/actions/runs/11903322842/job/33170050358

Then why is it not happening in the CI either? https://github.com/agronholm/apscheduler/actions/runs/11903322842/job/33170050358

These CI systems probably already come with several requirements installed. (Docker type that is already installed)

[agronholm]

The log output does not support that supposition:

Could this be an artifact of missing libpq5 or something? Could you try to import/use psycopg directly to see what error you get?

[agronholm]

Reading the installation docs, it seems clear that libpq5 is indeed required always, and is probably missing from your local system.

[agronholm]

This is what I get when trying to import psycopg in a container running python:3.12-slim:

>>> import psycopg

[HK-Mattew]

Reading the installation docs, it seems clear that libpq5 is indeed required always, and is probably missing from your local system.

Exactly that, the lack of this requirement in the system caused pytest to skip the tests related to psycopg, claiming that it was not installed.

Therefore, adding the extra binary solves these operating system requirement problems.
