I applied your patches at top of master. After tests corrections
(related to TID ordering in index relations DROP...CASCADE operation)
'make check-world' passed successfully many times.
In the case of 'create view' regression test - 'drop cascades to 62
other objects' problem - I verify an Álvaro Herrera hypothesis [1] and
it is true. You can verify it by tracking the
object_address_present_add_flags() routine return value.
Some doubts, however, may be regarding the 'triggers' test.
May you specify the test failures do you mean?
