temporal_tables VS rust_sqlite

There is also the temporal_tables extension.

I haven't used any of these but I work on https://xtdb.com which is also implementing SQL:2011's temporal features :)

It seems like PG has this extension here anyone ever use it?

You could look at that or ask me questions about it (disclaimer, I am the author). Also there is https://github.com/arkhipov/temporal_tables/

All good. Note there is also https://github.com/arkhipov/temporal_tables/ (which is also type 4 as a postgres extension - pretty similar to what ebean orm is doing)

The Temporal Tables Postgres extension works well. https://github.com/arkhipov/temporal_tables

If you're doing this across regions, you really really should reconsider. If you're doing it in the same data center you might be able to get away with it (but then I'm not sure why you're doing it in the first place, if the system fits in one DC then you probably can just scale up). It might be worth considering a sharded & passively combined approach -- i.e. every country has it's own data, and there's some huge public schema which consists of all the data that is drip fed in to materialized views or tables at regular intervals. You could also combine this with temporal_tables to get a very delayed but theoretically time-consistent (well, aside from clock skew across regions of course...) view of your DB to query... Really depends on the use case.

One of postgres's most underrated features. RLS is amazing, can be unseen/basically work silently if your programming language-side tools are good enough, and is documented well (like everything else):

But the power of PG is that it doesn't stop there, if you combine this with a plugin like temporal_tables and you can segment by user and time:

All of this mostly unknown to the thing that's accessing the DB. If that's not enough for you, why not add some auditing with pgaudit:

I think it might not actually be hyperbole to say that Postgres is the greatest RDBMS database that has ever existed.

You may have noticed that throughout the entire code I am making reference to a SQLRiteError type. That is an error type I defined as an enum using the thiserror crate, that is a super easy to use library that provides a convenient derive macro for the standard library’s std::error::Error trait. If you check the commits in the github repository, you may notice that I first wrote my own implementation of the std::error::Error trait. But then I bumped into this trait, that basically takes care of a lot of the boiler plate, and let’s face it, the code looks super clean! This is our error module so far, located in src/error.rs .

Also check out the github repo: https://github.com/joaoh82/rust_sqlite

I assume that if you are trying to follow this and writing some code along with me you can manage to create an empty Rust project on your own. Just to be clear this is what I did to start: cargo new rust_sqlite --bin . But again, you can find all the code on Github.
