I wonder if it's possible that you sent the wrong version of this
patch, because:
(1) The docs don't build with this applied. I'm not sure if it's the
only problem, but <glossterm linkend="glossary-db-cluster" is missing
the closing >.
(2) The changes to monitoring.sgml contain an unrelated change, about
pg_stat_all_indexes.idx_scan.
Also, I think the "For more information, see <xref linkend="whatever"
/> bit should have a period after the markup tag, as we seem to do in
other cases.
One other thought is that the incremental backup only replaces
relation files with incremental files, and it never does anything
about FSM files. So the statement that it only contains data that was
potentially changed isn't quite correct. It might be better to phrase
it the other way around i.e. it is like a full backup, except that
some files can be replaced by incremental files which omit blocks to
which no WAL-logged changes have been made.
