This is a doc oversight.  While working on the support of extstats
for this release, I have looked at holes like this one in the docs,
and did not consider the pattern of a linkend based on
sql-createstatistics.

The report mentions pg_dump, but we have the same wrong pattern in the
doc pages for pg_dumpall and pg_upgrade, leading me to the attached
for these three holes.

Thoughts?
