Add support for using an external database instead of a local database running on Central Server. Starting from version 6.23.0 it is possible to configure database connection details during Central Server installation. By default, local database is assumed during installation.
Remove explicit Postgres-BDR 1.0 (Bi-Directional Replication for PostgreSQL) dependency from Central Server. After the change Central Server does not provide out-of-the-box HA database solution, and therefore, setting up a HA database cluster is the responsibility of the Central Server operator.
Add a migration guide for migrating from from the current BDR based Central Server HA setup to an external DB cluster based setup. The migration guide explains the steps that are required to migrate Central Server cluster from a BDR based HA setup to an external DB cluster based setup.
