Is this a bug in pg_current_logfile() on Windows?

[Thomas Kellerer]

Hello,

I noticed the following strage output when running Postgres 12.3 (not psql) on 
Windows

    postgres=# select pg_current_logfile();
             pg_current_logfile
    ------------------------------------
     pg_log/postgresql-2020-07-08.log\r
    (1 row)

Note the "\r" at the end of the file name.

This does not happen when running Postgres on Linux.

Is this intended for some strange reason?
Or a bug or a technical limitation?

Regards
Thomas
