FWIW, this looks the same issue I am getting (reported last month:
https://www.postgresql.org/message-id/f444a84e-2d29-55f9-51a6-a5dcea3bc253%40burgess.co.nz)

I get the same Process Monitor output, including BUFFER OVERFLOW
entries.  No sign of any process other than postgres.exe touching the
WAL files.

Regards,

Guy
