Yes, fix is at the right place. We can not set the varlevelsup to the
correct value in replace_properties_references itself because when
that function is called, we do not know whether UNION is required or
not. The next place to adjust varlevelsup is when creating a UNION
statement.
Depending upon the varno of outer reference we will see different
symptoms. a crash or an error "plan should not reference subplan's
variable" or even data type mismatch. Also the levelsup is maintained
in nodes other than Var. I have modified the commit message to focus
on the problem instead of the symptom. Also some small edits to the
comments.
Attached patch has the number 0010 (vs 0001) since I am creating
patches for all the SQL/PGQ fixes from the same branch. It can be
applied independent of other patches.
