Footnotes

1. These are tests that we're marking as Successful, however they do not match the expected output in some way. This is due to small differences, such as different wording on the error messages, or the column names being incorrect while the data itself is correct. ↩

Thanks for the good test, but two things:

1. This should go in testing/postgres-client-tests
2. It should run on every PR, not nightly

LGTM, thanks for the changes
