Some <command>repmgr daemon ...</command> commands have been renamed to

<para>
|

For example, in &repmgr; 4.4 and earlier, the following <filename>repmgr.conf</filename>
|
||||
entry was valid:
|
||||
<programlisting>
|
||||
conninfo=host=node1 user=repmgr dbname=repmgr connect_timeout=2</programlisting>
|
||||
This must now be changed to:
|
||||
<programlisting>
|
||||
conninfo='host=node1 user=repmgr dbname=repmgr connect_timeout=2'</programlisting>
|
||||
</para>
|

<para>
|
||||
Note that simple string identifiers (e.g. <literal>node_name=node1</literal>)
|
||||
may remain unquoted, though we recommend always enclosing
|
||||
strings in single quotes.
|
||||
</para>
|
||||
<para>
|
||||
Additionally, leading/trailing white space between single quotes will no longer
|
||||
be trimmed; the entire string between single quotes will be
|
||||
taken literally.

<para>
|
||||
Strings enclosed in double quotes (e.g. <literal>node_name="node1"</literal>)
|

will now be rejected; previously they were accepted, but the double quotes were
|
||||
interpreted as part of the string, which was a frequent cause of confusion.
