Buckets have a lot of features that postgres don’t. Like mounting via FUSE. And Garage in particular offers some integrations to apps, websited, and so on. I would go with this instead of having a column of byte data in a DB table. The pgsql solution might work in small and simple cases (e.g. storing the user’s avatar in a forum) but even so, if I could or had to choose, I wouldn’t do it.
