Basic changes like #3030 wait 20m before they're merged. The culprit is hefty postgres and windows integration tests.

These tests are probably difficult to speed up. P

The most notable caveat to path based filtering is the action may use scripts and files outside of the main language. For example, a go test action may use a test.sh script and a Makefile. If we decide to use path filtering, we should do so sparingly, as there's an inescapable trade off between speed and correctness.

Definition of done

improve CI speeds from (20m?) to (?). One suggested path: we could use path based filtering or different triggers (cron or master only) to speed up the average Pull Request?
