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
