alt Hacker NewsCan you use postgres as a state store for a distributed application?
It seems this article is trending toward that view: If you can maintain transactional consistency along with application workflow state, then would this generalize to maintaining distributed application state in general?
The follow-up would be: Would this be preferable to Valkey/Redis?

Yes, in the sense of 'too good to be true'

Yes you can - usually I think it's advisable to wrap postgres in a shim application to provide a consistently defined surface you can control but postgres can absolutely serve as the authority node on data correctness.
As to which technical solution would be optimal there are a bunch of factors to consider and I think preferences around features could lead you to a variety of options. Postgres is excellent as long as you're minimizing the amount of data piping directly through it or operating at a reasonable scale.
