Pgbouncer maintainer here. Overall I think this is a great description of the tradeoffs that PgBouncer brings and how to work around/manage them. I'm actively working on fixing quite a few of the issues in this blog though

1. Named protocol-level prepared statements in transaction mode has a PR that's pretty close to being merged: https://github.com/pgbouncer/pgbouncer/pull/845

2. SET/RESET tracking in transaction mode. For this we need some changes in the postgres protocol to ask for postgres to tell pgbouncer about setting updates. This is being worked on here: https://www.postgresql.org/message-id/flat/CAGECzQQOOhH1Rztu...

3. The single threading issue can be worked around by using multiple processes that listen on the same port using so_reuseport=1 https://www.pgbouncer.org/config.html#so_reuseport

4. The pg_dump issue can actually be solved already by installing the Citus extension and using track_extra_parameters (otherwise you have to wait for the same postgres protocol addition that's needed for the other SET/RESET commands) https://www.pgbouncer.org/config.html#track_extra_parameters
