I hereby claim:

To claim this, I am signing this object:

Object life time: the implicit contract between functions and objects

What expectations does F have about its parameter E?

void F(CExpression *E) {
  do_something_with_E(...);

Our tests for pg_upgrade is its own travesty:

It takes no control over its input: let's upgrade whatever is left in the cluster. That means we really don't know how or what we are testing.
It relies on comparing two dumps (one before upgrade, one after upgrade) and asserting that they are verbatim identical. Philosophically speaking, this is sufficient not necessary. Practically, this is wrong.
