Hey folks, trying to run the datahike tests locally with clj -A:test -m kaocha.runner --watch and getting:

[(.....)(......)([watch] Fatal error in test run #error {

It seems to be complaining about a Postgres backend that I assume doesn't exist, as I definitely did not do anything manually to set up a Postgres db. Was going to try to start on the PR I mentioned on Wednesday...thoughts? The https://github.com/replikativ/datahike/blob/development/doc/contributing.md doesn't mention anything about how to run tests.
