Reconfiguring an RCS

There is no one-click reconfiguration of a running RCS. To change its configuration, edit each member cluster — starting with the primary.

General configuration

Edit postgresql.conf on the cluster form, then click Push Config. Files to Server.

Updating a cluster's general configuration

Replication configuration

Same procedure, from the cluster's Replication tab.

Updating the replication configuration

Network access

Access rules are the exception — they are applied set-wide. Reconfigure RCS Access, under Security on the RCS's Configuration tab, rewrites UFW and pg_hba.conf on every member.

Use it after adding a member, moving a Host, or changing the replication user.
