Both of those changes are the result of volatile CTEs being inlined more
than once (in one case, as part of an explicit test to ensure that CTEs
are being materialized and not multiply evaluated).
If you look for the XXX comment in the patch, it should be easy to add a
check that skips inlining if cterefcount > 1 and
contains_volatile_functions is true.
