Crunchy Bridge allows you to customize each cluster in a number of ways to suit your specific needs. The cluster settings outlined below can be freely changed without causing any downtime or service interruption.
Cluster Name setting
A cluster’s name can be changed at any time in the Cluster Settings page:
High Availability setting
High Availability (HA) can be turned on or off for any cluster from the Cluster Overview page:
HA can be enabled for any cluster regardless of its size or other properties. This will create a special replica that will replace the cluster in case of a failure. You can learn more on the High Availability page.
Maintenance Window setting
The maintenance window for a cluster can be set or removed on the Cluster Settings page:
Read more about Maintenance Windows.
You can enable a flag called Protected on any cluster in the Cluster Settings page. This makes it impossible to destroy the cluster (until the flag is unset).
Some aspects of a cluster can only be changed through Cluster Management maintenance operations. These operations require maintenance and should be initiated with care:
- Resizing the plan and/or disk
- Upgrading Postgres version
- Suspending or Resuming the underlying database server
Other aspects of a cluster cannot be changed directly, including:
- Team ownership of a cluster
- Provider or region where a cluster is provisioned
If you do want to change cluster ownership, or the provider or region where a cluster is provisioned, you have a couple of options. For clusters that are small in size and not being used in production, the easiest method is to use
pg_dump to export the contents of the old cluster and
pg_restore to import the contents into a newly provisioned cluster in the correct Team.
For larger or production databases, contact support and we can work with you on another method.
