pg_autoctl perform switchover
pg_autoctl perform switchover - Perform a switchover for given formation and group
This command starts a Postgres switchover orchestration from the pg_auto_switchover monitor:
usage: pg_autoctl perform switchover [ --pgdata --formation --group ] --pgdata path to data directory --formation formation to target, defaults to 'default' --group group to target, defaults to 0
The pg_auto_switchover monitor can be used to orchestrate a manual switchover, sometimes also known as a switchover. When doing so, split-brain are prevented thanks to intermediary states being used in the Finite State Machine.
pg_autoctl perform switchover command waits until the switchover is
known complete on the monitor, or until the hard-coded 60s timeout has
The switchover orchestration is done in the background by the monitor, so even
pg_autoctl perform switchover stops on the timeout, the switchover
orchestration continues at the monitor.
