pgAdmin 4: "PostgreSQL Binary Path" empty

Hi,

this is a request for enhancement plus a support question.

With PostgreSQL 9.6 RC 1 (i.e. pgAdmin 4 1.0-rc1) I cannot restore a
database backup, since in preferences, the field "Paths > Binary paths >
PostgreSQL Binary Path" is empty.

Which binary (on Windows) is supposed to go in there? Please tell me and
also explain this on https://www.pgadmin.org/docs4/dev/preferences.html

And wouldn't it be possible to detect the path automatically?

Thanks!!

Cheers,
Thomas
