@aldent95 no tests were failing because of this error? Can we write a test that would have failed in this case?

There were tests that I've updated in this PR. But that relies on the correct argument being in the test as well. The only way to truly test it would be to actually have tests that run pg_dump itself.
Being a first time contributor I don't have enough knowledge of the CI/CD Rails uses to know if that's even possible.

#44069 implements this idea.
