]I'm having a similar issue. I created the postgres server on the host machine (kept DaVinci's default settings for its setup), enabled sharing, and created an access key on a shared folder.
On the client machine, I dragged the access key file into the project manager, at which point it did nothing. When I tried dragging it in again, a dialogue popped up saying "Database already Exists" but it does not show up in the left-hand database list.

I'm not a genius on postgres, but I'm hoping there's something simple I'm doing wrong here. Thoughts?
