No default for (user-specific) service file location on Windows?

Hi,

The doc is explicit about defaults for the password file:
From https://www.postgresql.org/docs/current/libpq-pgpass.html
Linux: ~/.pgpass
Windows: %APPDATA%\postgresql\pgpass.conf

But for the service file OTOH, only the Linux default is documented:
From: https://www.postgresql.org/docs/current/libpq-pgservice.html
Linux: ~/.pg_service.conf
Windows: N/A

I tried the obvious %APPDATA%\postgresql\pg_service.conf, with no luck.

So is this a lack in the documentation for the service file?
Or is it instead a lack of symmetry in the implementations of these
two mechanisms?

If the latter, any chance the symmetry would be restored? (with
corresponding doc update).

I guess the only work-around specific to Windows at this point, if the latter,
would be defining the PGSERVICEFILE env-var explicitly? --DD
