+ 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.
