Pull Request #118 refactored by Sourcery.

Since the original Pull Request was opened as a fork in a contributor's repository, we are unable to create a Pull Request branching from it.

To incorporate these changes, you can either:

1. Merge this Pull Request instead of the original, or

2. Ask your contributor to locally incorporate these commits and push them to the original Pull Request

   Incorporate changes via command line

   git fetch https://github.com/supabase-community/postgrest-py pull/118/head
   git merge --ff-only FETCH_HEAD
   git push

NOTE: As code is pushed to the original Pull Request, Sourcery will re-run and update (force-push) this Pull Request with new refactorings as necessary. If Sourcery finds no refactorings at any point, this Pull Request will be closed automatically.
