Whitespace is insignificant (except within a quoted parameter value) and blank lines are ignored.

Parameter values that are not simple identifiers or numbers should be single-quoted.

Beginning with <link linkend="release-5.0">repmgr 5.0</link>, configuration

The main change is that &repmgr; requires most string values to be
enclosed in single quotes. For example, this was previously valid:
<programlisting>
conninfo=host=node1 user=repmgr dbname=repmgr connect_timeout=2</programlisting>
but must now be changed to:
<programlisting>
conninfo='host=node1 user=repmgr dbname=repmgr connect_timeout=2'</programlisting>
