potiuk opened a new pull request, #34293:
URL: https://github.com/apache/airflow/pull/34293
Some of the recent sqlalchemy changes are not working with minimum version
of sqlalchemy of ours - for example `where` syntax does not allow moe than one
clause and we are already passing more in _do_delete_old_records (added in
#33527). This syntax however was added in SQL Alchemy 1.4.28 and our minimum
version was 1.4.27.
This change bumps the minimum SQLAlchemy version to 1.4.28 but it also adds
a special test job that only runs on Postgres that downgrades the SQLAlchemy to
the minimum supported version (retrieved from setup.cfg). This way, we will be
able to detect such incompatible changes at the PR time. This is a new flag
`--downgrade-sqlalchemy` on test command that works similar to earlier
`--upgrade-boto`.
We also enable the `--upgrade-boto` and `--downgrade-sqlalchemy` flags to be
used for `breeze shell` command - thanks to that we can easily test both flags
with `breeze shell` command.
