According to https://elements.heroku.com/addons/heroku-postgresql the instances they're using for this tier have zero bytes of RAM, so presumably that's where they're getting most of their cost savings from.

I'm assuming this means that they are not providing any sort of guarantee on the amount of RAM available and packing these instances as tightly as they can.

I like to think they just aren't installing any RAM in the servers and running all the databases out of L3 cache
