Oh no, @codecov-io is back with its erroneous reports. Anyone have experience in disabling or fixing?

Thanks @max-sixty and @msegado!

Regarding the fact that float doesn't work well for identifiers, I agree, but I think being consistent with Pandas is more important. People can always cast to string in their SQL if they want to preserve IDs.

[msegado]

Very welcome! And yes, I agree that it was a reasonable decision to match the Pandas behavior.
