NAME

6       pg_autoctl enable monitor - pg_autoctl enable monitor
7
8       pg_autoctl  enable  monitor  - Enable a monitor for this node to be or‐
9       chestrated from
10

SYNOPSIS

12       It is possible to disable the pg_auto_failover monitor  and  enable  it
13       again  online in a running pg_autoctl Postgres node. The main use-cases
14       where this operation is useful is when the monitor node has to  be  re‐
15       placed,  either after a full crash of the previous monitor node, of for
16       migrating to a new monitor node (hardware replacement, region  or  zone
17       migration, etc).
18
19           usage: pg_autoctl enable monitor  [ --pgdata --allow-failover ] postgres://autoctl_node@new.monitor.add.ress/pg_auto_failover
20
21          --pgdata      path to data directory
22

OPTIONS

24       --pgdata
25              Location of the Postgres node being managed locally. Defaults to
26              the environment variable PGDATA. Use --monitor to connect  to  a
27              monitor from anywhere, rather than the monitor URI used by a lo‐
28              cal Postgres node managed with pg_autoctl.
