The first thing you should do when you find this is to see if there is a
buildfarm report of the failure. If there isn't then try to work out why.

Sorry, I will have to research the buildfarm, I have no reference to it.

 

Also, when making a report like this, it is essential to let us know
things like:

  * which commit is causing the failure (git bisect is good for finding
    this)

Thanks for hit (git bisect).

 

  * what Windows version you're testing on

Windows 10 (2004)

  * which compiler you're using

msvc 2019 (64 bits)

Only for registry, if anyone else is using msvc 2019.

I'm using latest msvc 2019 64 bits (16.6.0)

Problably this is a compiler optimization bug.

vcregress check with build DEBUG, pass all 200 tests.

With the current HEAD, the regression float8 in release mode (msvc 2019 64 bits) is gone.
Maybe it's this commit:
https://github.com/postgres/postgres/commit/0aa8f764088ea0f36620ae2955fa6c54ec736c46

But (partition_prune) persists.
