Yes, the problem was introduced in

Author: Alvaro Herrera <alvherre(at)alvh(dot)no-ip(dot)org>
Branch: master [3b97e6823] 2013-12-16 11:29:50 -0300
Branch: REL9_3_STABLE [8e9a16ab8] 2013-12-16 11:29:51 -0300

Rework tuple freezing protocol

and 9.3.2 had been tagged two weeks earlier (strangely, I don't see
"Release: 9.3.2" in git_changelog output, even though I just pulled).
So only people using a git checkout would see it.

Maybe this doesn't event warrant a release note entry.
