Happy pgdog user here, I can recommend it from a user perspective as a connection pooler to anyone checking this out (we're also running tests and positive about sharding, but haven't run it in prod yet, so I can't 100% vouch for it on that, but that's where we're headed.)

@Lev, how is the 2pc coming along? I think it was pretty new when I last checked, and I haven't looked into it much since then. Is it feeling pretty solid now?

It feels better now, but we still need to add crash protection - in case PgDog itself crashes, we need to restore in-progress 2pc transaction records from a durable medium. We will add this very soon.
