Thank you for contributing to CockroachDB. Please ensure you have followed the guidelines for creating a PR.

Before a member of our team reviews your PR, I have some potential action items for you:

• We notice you have more than one commit in your PR. We try break logical changes into separate commits, but commits such as "fix typo" or "address review commits" should be squashed into one commit and pushed with --force
• When CI has completed, please ensure no errors have appeared.

I was unable to automatically find a reviewer. You can try CCing one of the following members:

• A person you worked with closely on this PR.
• The person who created the ticket, or a CRDB organization member involved with the ticket (author, commenter, etc.).
• Join our community slack channel and ask on #contributors.
• Try find someone else from here.

🕐 Waiting for PR status (Github check) to be set, probably by CI. Bors will automatically try to run when all required PR statuses are set.

GitHub status checks took too long to complete, so bors is giving up. You can adjust bors configuration to have it wait longer if you like.
