The default for python is to buffer stdout, which means that log lines might now show up in the output straight away (until a certain number of lines or number of bytes of output have been written) -- this is especially problematic if the pre-migration checks taking a long time as it makes it look like it has hung

The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease. |

The default for python is to buffer stdout, which means that log lines might not show up in the output straight away (until a certain number of lines or number of bytes of output have been written) when stdout is not a TTY -- this is especially problematic if the pre-migration checks taking a long time as it makes it look like it has hung.
