PGACTIVE

Summary from the TLDR newsletter

pgactive is a PostgreSQL replication extension for creating an active-active database. PostgreSQL added native support for logical replication in PostgreSQL 10 in 2017, but it still requires additional features to fully support an active-active replication topology. Its design makes it possible to build the necessary components for supporting active-active replication in an extension while the development community continues to add it into the upstream project.
