pg_receivewal.exe unhandled exception in zlib1.dll

Hello,

If you execute pg_receivewal.exe with the option "--compression-method
gzip" it will fail with no error. You can see an error in the db log:

2022-02-10 11:46:32.725 CET [11664][walsender] [pg_receivewal][3/0:0] LOG:
could not receive data from client: An existing connection was forcibly
closed by the remote host.

Tracing the execution you can see:

Unhandled exception at 0x00007FFEA78C1208 (ucrtbase.dll) in An invalid
parameter was passed to a function that considers invalid parameters fatal.

The problem comes from the file descriptor passed to gzdopen() in
'src/bin/pg_basebackup/walmethods.c'. Using gzopen() instead, solves the
issue without ifdefing for WIN32. Please find attached a patch for so.
