This makes it possible to return log output when executing repmgr
remotely at a different level to the one defined in the remote
repmgr's repmgr.conf.
This is particularly useful when DEBUG output is required.
"repmgr daemon" can be interpreted to mean the commands affect the local
daemon process only. Rename the commands which affect the entire cluster
to "repmgr service ...".
The "repmgr daemon ..." form of the affected commands is retained for backwards
compatibility.
The following options have long since been deprecated, and any attempt
to use them results only in a warning that they are no longer valid:
--data-dir
--no-conninfo-password
--recovery-min-apply-delay
Previously, repmgr was using a very simple ad-hoc string-based parser,
which had various limitations and allowed configuration files to be
created in a way which could cause confusion and/or unexpected
behaviour.
For example, it accepted strings enclosed in single quotes, but treated
strings enclosed in double quotes literally. A node_name defined thusly:
node_name="somenode"
would result in the literal value '"somenode"' being used, which could
lead to unobvious errors along the lines of:
no record found for ""somenode""
The configuration file parser has been adapted from the one used by
PostgreSQL itself, so behaves more-or-less identically (though some
functions such as file inclusion are not supported in repmgr).
This makes configuration parsing more robust and consistent;
additionally, error reporting will be more precise.
Note this does mean that some repmgr.conf items previously accepted
as valid by repmgr will now be rejected; in particular this includes
strings containing spaces which are not enclosed in single quotes.
This reverts commit c6ca183247.
Backing out this patch for now as the Debian build system doesn't
seem to like it, even though it builds just fine on Debian itself.
This should be used wherever we need to show the latest release
date.
Don't use this in the release notes however, as it will be easy to
forget to update it when adding notes for a new release.
Use &repmgrversion; entity to generate the current version number and
prevent document bitrot.
Also define a "release-current" ID attribute for ease of linking to
the current release notes.

While it's technically possible to have a standby follow another
standby while the primary is not available, repmgr will not be able
to update its metadata, which will cause Confusion and Chaos.
Update the documentation to make this clear, and provide a more helpful
error message if this situation occurs. The operation previously
failed anyway, but with an unhelpful message about not being able to
find a node record.
