I have to say I have a disliking for what appears to be the current trend of marketing things as "postgres (wire) compatible". CockroachDB is another example that does the same.
The implication is that "if you can do it in postgres, you can do it in X". But the reality is, of course, different.
If you are using databases properly, not just as a blackbox dumping ground, then if you use postgres on the wire, its because you are talking to postgres and using postgres specific features (like you should).
Unless you have feature parity, don't tell me I can connect to another database using my postgres libraries. Its pointless. Its meaningless. Why would I want to do that if I can't use the features ?

Rant over. ;-)
