Hi. With a recent xmllint (using libxml version 21500-GITv2.15.0), doc
compilation fails with:
/usr/bin/xmllint --nonet --path . --path . --output postgres-full.xml --noent
--valid postgres.sgml
ref/pg_combinebackup.sgml:317: validity error : standalone: normalization of
attribute linkend on xref by external subset declaration
state of the cluster using <xref linkend="app-pgchecksums "/> is
^
Attached a patch to solve the issue.

To avoid this problem, taking a new full backup after changing the checksum
- state of the cluster using <xref linkend="app-pgchecksums "/> is
+ state of the cluster using <xref linkend="app-pgchecksums"/> is
recommended. Otherwise, you can disable and then optionally reenable
checksums on the directory produced by <literal>pg_combinebackup</literal>
in order to correct the problem.
