When trying to insert a tuple into a partitioned table, the routing to
the correct partition has been messed up by mixing when a tuple needs to
be stored in an intermediate parent's slot and when a tuple needs to be
converted because of attribute changes between the immediate parent
relation and the parent relation one level above that (the grandparent).
This could trigger errors like the following:
ERROR: cannot extract attribute from empty tuple slot SQL state: XX000
This was not detected because regression tests with dropped attributes
only included tests with two levels of partitioning, and this can be
triggered with three levels or more.
This fixes bug #15733, which has been introduced by 34295b8. The bug
happens only on REL_11_STABLE and HEAD gains the regression tests added
for this bug.
