<para>
Path to the PostgreSQL binary directory (location of <application>pg_ctl</application>,
<application>pg_basebackup</application> etc.). Only required
if these are not in the system <varname>PATH</varname>.
</para>
<tip>
<para>
When &repmgr; is executed via <application>SSH</application> (e.g. when running
<command><link linkend="repmgr-standby-switchover">repmgr standby switchover</link></command>,
<command><link linkend="repmgr-cluster-matrix">repmgr cluster matrix</link></command> or
<command><link linkend="repmgr-cluster-crosscheck">repmgr cluster crosscheck</link></command>,
or if it is executed as cronjob), a login shell will not be used and only the
default system <varname>PATH</varname> will be set. Therefore it's recommended to set
<varname>pg_bindir</varname> so &repmgr; can correctly invoke binaries on a remote
system and avoid potential path issues.
</para>
</tip>
<para>
Debian/Ubuntu users: you will probably need to set this to the directory where
<application>pg_ctl</application> is located, e.g. <filename>/usr/lib/postgresql/9.6/bin/</filename>.
</para>
<para>
<emphasis>NOTE</emphasis>: <varname>pg_bindir</varname> is only used when &repmgr; directly
executes PostgreSQL binaries; any user-defined scripts
<emphasis>must</emphasis> be specified with the full path.
