<para>
Fix incorrect handling of equivalence-class tests in multilevel
nestloop plans (Tom Lane)
</para>
<para>
Given a three-or-more-way equivalence class of variables, such
as <literal>X.X = Y.Y = Z.Z</>, it was possible for the planner to omit
some of the tests needed to enforce that all the variables are actually
equal, leading to join rows being output that didn't satisfy
the <literal>WHERE</> clauses. For various reasons, erroneous plans
were seldom selected in practice, so that this bug has gone undetected
for a long time.
