chore: fix windows postgres tests (#15593)

hugodutka · web-flow · commit 6ed76921ddb6 · 2024-11-20T13:30:31.000+01:00
Patches tests that caused Windows Postgres CI in #15520 to consistently fail. I tested this by temporarily adding Postgres Windows CI to this PR. However, I reverted those changes to merge them with #15520. For reference, here's [a passing CI run](https://github.com/coder/coder/actions/runs/11918816662/job/33219786238) from an earlier commit. **Note:** Although Windows tests now pass, they remain quite flaky. I recommend running Postgres Windows CI to gather data on these flakes, but I don’t think it should be a required job just yet.
