Stability dashboard seems to pull in things it shouldn't

[sfackler]

Nothing in rust-postgres has been marked with any stability annotations, but the rustdoc stability summary shows it being 12% stable: http://sfackler.github.io/rust-postgres/doc/postgres/stability.html

The stability attributes aren't meant for anything but rustc. Doesn't mean this isn't a bug, but just sayin'.

Currently, when you impl a trait, if you don't provide a stability marker on the impl it will default to the stability of the trait. This was a workaround for #[derive], where you cannot provide your own stability marker.

I'm pretty sure what you're seeing here is just stable implementations for standard traits.

Closing in favor of #18969
