"One thing I would say about postgres is that it has a lot of features. As a new user, it's hard to know which ones to use in which ways, and what the downsides might be."

Do you have some suggestions how that can be improved? Are there features that you would classify as "bloat" or that seem confusing or poorly documented?

Postgres is a very general system and has a large variety of users as a result. That means that the features tend to be very well-thought out and don't carry a lot of surprises, but it also means that it's hard to guide users toward specific usage patterns. Even among web users, a feature like LISTEN/NOTIFY might be an instrumental part of the caching infrastructure for some users, but seem like bloat to others.
