The documentation links to bigsql.org I believe. I don't have the help file handy but either way, this gets redirected and in the end you get to a spot to download the Postgres but it isn't the same as depicted. I'm thinking I missed some grant values. It is hard to test this as you must take over the console if installing on another system which is my case. There is no try before buy and this IMHO means that you either need a second license or the company must be out of business for troubleshooting. I tried to get them to allow me to force calls to a deskset but the operator didn't want this. Another Mitel fail.
