I hope the method with the environment variables will hold on.

For security reasons it is much better to use the variable method with
PGPASSWORD. I can set the environment hidden from any user by a program.
The .pgpass is readable for any admin, opposed to the statement in the docs:
"On Microsoft Windows, it is assumed that the file is stored in a directory
that is secure, so no special permissions check is made."

Regards
Walter
