Checklist

• If I added new functionality, I added tests covering it.
• If I fixed a bug, I added a regression test to prevent the bug from silently reappearing again.
• I added code comments for anything non trivial.
• I added documentation for my changes.
• If I added/changed/removed ENV var, I submitted a PR to https://github.com/celo-org/monorepo to update the list and default values of env vars.
• If I add new indices into DB, I checked, that they are not redundant with PGHero or other tools.
