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.
