From 1293b21b2defd151a43a62f84c42e1f745b187bb Mon Sep 17 00:00:00 2001 From: Nathan Sobo Date: Tue, 26 Apr 2022 13:30:21 -0600 Subject: [PATCH] Get db tests passing with Tokio Postgres adaptor We now run tests that interact with the real database under a Tokio reactor. We make the tests run multi-threaded so we can block on the main thread on database teardown and still make progress actually tearing down the DB.
