pgAdmin 4: "PostgreSQL Binary Path"?

Hi,

which binary (on Windows) is supposed to go in the field "Paths > Binary 
paths > PostgreSQL Binary Path"?


Details:
I have PostgreSQL 9.6 RC 1 (i.e. pgAdmin 4 1.0-rc1), downloaded from 
http://www.enterprisedb.com/products-services-training/pgdownload#windows 
running on Windows 10 x64.

And when I'm trying to restore a database backup, I get the error 
message "Please configure the PostgreSQL Binary Path in the Preferences 
dialog."

Thanks!!


Cheers,
Thomas
