NAME

pg_autoctl show standby-names - pg_autoctl show standby-names

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

SYNOPSIS

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

OPTIONS

--pgdata: 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.
--monitor: 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.
--formation: Show the current synchronous_standby_names value for the given formation. Defaults to the default formation.
--group: Show the current synchronous_standby_names value for the given group in the given formation. Defaults to group 0.
--json: Output a JSON formatted data instead of a table formatted list.
