HAProxy and PGBouncer can do load balancing for reads, but ultimately the cluster is single main for writes.
Supabases Supavisor is another beta release option for postgres connection routing, but it is VERY early in development. I think they are dog-fooding it tho. Certainly one I am keeping an eye on!

However, that is my limited experience opinion.
Happy to be told otherwise, hopefully I start a discussion!

thank you! I'm too tired to contribute to a discussion right now 😅

been experimenting with postgres to hopefully move to it eventually.

I use mariadb at the moment and they've been releasing pretty unreliable updates in recent years. Galera was nice with it, but had way too many issues.

If you're looking for a mysql/maria drop-in replacement, then you may also want to look at tidb

postgres can do it, but it's kind of presented as lego blocks for a HA cluster and often requires making your own tooling if you want sophisticated features like placement index instances and rebalancing

query optimization and the similar structure to SQL server with schemas pulls me towards postgres, got another system using SQL server with upwards of millions of records and need it to be fast and reliable
