Creating Clusters

Clusters are created from the PostgreSQL tab of the Host form (Muppy / Hosts / Hosts).

1. Click Create Cluster. The cluster creation wizard opens.
2. Set the Version, Name, network Port and Locale.
3. Click Launch.

When it finishes, click Refresh on the Host. The new cluster appears in the list at the bottom of the PostgreSQL tab.

The Version defaults to the value set in Settings / PostgreSQL / PostgreSQL version (system parameter muppy_postgresql_base.default_postgresql_version, shipped as 18). Muppy installs that PostgreSQL version on the Host if it is missing.

New clusters are not started

A new cluster is left in state Down, so you can configure it before it accepts connections.

Where to find clusters

• On the Host form, PostgreSQL tab.
• Under Muppy / Databases / PostgreSQL / Database Clusters, which lists every cluster Muppy manages. This is the more convenient entry point.
