Is there anything like Galera for PostreSQL? I find it very convenient for small-scale HA and redundancy and it's quite easy to get going.

Not for free (have to pay EnterpriseDB for that). Every free option here is basically "glue pieces together to build your own HA".

I am not sure exactly what Galera does, but you may want to look into Citus (https://www.citusdata.com/).

Citus is great, however do note that reading the docs you do have to change your scheme to use Citus. So it's not really "drop-in" par say.

I don't know much about Galera, but Patroni may be of interest to you

Galera is multi-master but I'm not sure that's as important with Postgres (it has good baseline performance & can fail over quickly).

Patroni is great for managing active-hot standby clusters
