Request for SQL experts: Lemmy PR to combine action tables (github.com)

Lemmy currently uses distinct tables like post_like: (post_id, person_id, score) and post_saved. Unfortunately this causes performance issues when we have to join many of these tables to create views.

One suggestion in this PR, is to combine these into a single post_action table, with a lot of optional columns depending on the action. This solution scares me a little, because I'm afraid we might lose data integrity, and many of our constraints with so many optional columns.

Is there a better way of doing this in SQL?

Isn't that what genetic algorithms were about?
