FWIW, this looks the same issue I am getting (reported last month:

Yep.
I get the same Process Monitor output, including BUFFER OVERFLOW entries.
No sign of any process other than postgres.exe touching the WAL files.
Guy, do you have an environment where this is still happening and
where you could test a potential fix? We are not sure yet what's
causing that, but one code path has changed in this area, involving
CreateHardLinkA()+_unlink() instead of a single rename when attempting
to recycle a segment. And I am just in a mood to build things by
myself and send some links to people to be able to download and test
that, so one more is fine..
