I can answer this, as I purchased Postico for our team just today (just out of gratitude really, as the free version is good enough) Tunnelling via SSH works great, but you do have to provide and save your ssh key password in Postico, because it does not use ssh-agent. Lots of great features and small updates here and there: it was updated with touch bar support quite quickly. A killer feature is Ctrl+P fuzzy search for table names in database. It's great for getting query data out of your db quickly or just browsing around. Ok to add the odd column here and there. However managing roles and permissions seems to be out of scope.
