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.
The pg_autoctl perform switchover command waits until the switchover is known complete on the monitor, or until the hard-coded 60s timeout has passed.
The switchover orchestration is done in the background by the monitor, so even if the pg_autoctl perform switchover stops on the timeout, the switchover orchestration continues at the monitor.
See also pg_autoctl perform failover, a synonym for this command.
Location of the Postgres node being managed locally. Defaults to the environment variable PGDATA. Use --monitor to connect to a monitor from anywhere, rather than the monitor URI used by a local Postgres node managed with pg_autoctl.
Formation to target for the operation. Defaults to default.
Postgres group to target for the operation. Defaults to 0, only Citus formations may have more than one group.
