Control & Status¶
The header of the Database Cluster form carries the pg_ctlcluster commands. Which ones
appear depends on the cluster's current state.
| Button | State it appears in | What it does |
|---|---|---|
| Start | Down | Start the cluster. |
| Stop | Online | Stop the cluster. |
| Restart | Online | Stop then start. |
| Reload | Online | Reload the configuration without dropping connections. |
| Drop Cluster | Online or Down | pg_dropcluster — erases all data. |
| Upgrade Cluster | Online or Down | Upgrade the cluster to a newer PostgreSQL version. |
| Delete | Broken | Archive the Muppy record after PostgreSQL was removed outside Muppy. |
Each one asks for confirmation.
Update Facts refreshes the state of this cluster — and of every cluster on the same Host — by collecting its Facts.
Systemd unit¶
A cluster's systemd unit becomes available once you create a wrapper for it: on the Configuration tab, click Create Systemd Unit Wrapper.
