One day this will no longer be an issue, until then let's hope the fine documentation is read.

|
|
Promotes a standby to a primary if the current primary has failed. This
|
|
command requires a valid <filename>repmgr.conf</filename> file for the standby, either
|
|
specified explicitly with <literal>-f/--config-file</literal> or located in a
|
|
default location; no additional arguments are required.
|
|
</para>
|
|
<para>
|
|
If the standby promotion succeeds, the server will not need to be
|
|
restarted. However any other standbys will need to follow the new server,
|
|
by using <xref linkend="repmgr-standby-follow">; if <application>repmgrd</application>
|
|
is active, it will handle this automatically.
|
|
</para>
|
|
<para>
|
|
Note that &repmgr; will wait for up to <varname>promote_check_timeout</varname> seconds
|
|
(default: 60 seconds) to verify that the standby has been promoted, and will
|
|
check the promotion every <varname>promote_check_interval</varname> seconds (default: 1 second).
|
|
Both values can be defined in <filename>repmgr.conf</filename>.
