pg_autoctl show standby-names

pg_autoctl show standby-names - Prints synchronous_standby_names for a given group


This command prints the current value for synchronous_standby_names for the primary Postgres server of the target group (default 0) in the target formation (default default), as computed by the monitor:

usage: pg_autoctl show standby-names  [ --pgdata ] --formation --group

  --pgdata      path to data directory
  --monitor     pg_auto_failover Monitor Postgres URL
  --formation   formation to query, defaults to 'default'
  --group       group to query formation, defaults to all
  --json        output data in the JSON format



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.


Postgres URI used to connect to the monitor. Must use the autoctl_node username and target the pg_auto_failover database name. It is possible to show the Postgres URI from the monitor node using the command pg_autoctl show uri.

Defaults to the value of the environment variable PG_AUTOCTL_MONITOR.


Show the current synchronous_standby_names value for the given formation. Defaults to the default formation.


Show the current synchronous_standby_names value for the given group in the given formation. Defaults to group 0.


Output a JSON formated data instead of a table formatted list.
