Hi,
I found typos "pg_statistics" in REL9_6_STABLE, but that has been
fixed in the master branch.
Fix typo: pg_statistics -> pg_statistic
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=5a366b4ff4ceceb9793fcc13c3f097ee0d32c56d;hp=f7c62462402972b13d10e43f104ca0c0fecb6d08
I think it would be better to backport this to other branches.
Regards,
