Please find the attached patch for SQLAlchemy updates for check table is present in the database or not. (This will resolve load and dump server.)
How come this upstream change didn't fail the regression tests?
Flask-SQLAlchemy is dependent on SQLAlchemy and which is an indirect dependency of pgAdmin, so if the installed version of Flask-SQLAlchemy is the latest one, it will be skipped.
Sure, but the regression test runs on the buildfarm build the venv from scratch on every run (as happens when we build the packages themselves). So I can see why local regression runs might have passed (as developers generally don't recreate their venv's from scratch before testing), but I would expect to have seen failures on the buildfarm.
