  Discontinued PostgreSQL pooler with sharding, load balancing and failover support. [Moved to: https://github.com/postgresml/pgcat] (by levkk)

  

This is actually pretty amazing. I wouldn't normally trust a single author implemented project to sit between my application and my database, since that is a rather critical single point of failure. However, a grep that fails to find `unsafe` in a rust code base lets me know that this code is in fact pretty safe[1]. I don't need to trust the author, as much as I trust the Rust core team, and LLVM.

Since I can see basic functionality exercised in the test suites, and trust that Rust has validated its more general correctness, this gives me more confidence in your project than I would historically expect to be able to gather in such a short amount of time.

  Enhanced PostgreSQL logical replication (by kingluo)

You might want to consider a different name, as there's already a pgcat project which appears to be a logical replication extension to augment native logical replication.

  Prometheus exporter for PgBouncer

  

Pgbouncer does have stats, you can get them using the `SHOW STATS` family of commands. You can then either manually scrape them or use something like pgbouncer_exporter[1] for Prometheus.
