+ Fix mis-planning of repeated application of a projection step
+ (Tom Lane)
+
+
+
+ The planner could create an incorrect plan in cases where two
+ ProjectionPaths were stacked on top of each other. The only known
+ way to trigger that situation involves parallel sort operations, but
+ there may be other instances. The result would be crashes or
+ incorrect query results.
+ Disclosure of server memory contents is also possible.
