If I may share some advice - don't bother. As another commenter pointed out, relationships are inherent in a lot of the data you'll store for your platform, and for those elements that you'd like to keep the full data hash, just use jsonb in Postgres. Once you're at several million in revenue, then you can think about splitting off some parts of your data into document storage solutions for certain efficiency reasons, but that is by no means necessary.
