I've finally cleared my plate enough to start reviewing this patchset.

I think you should go ahead and push this tests-adding patch now, as it
adds documentation of the current behavior that is a good thing to have
independently of what the rest of the patchset does. Also, I'm worried
that some of the GROUP BY tests might have machine-dependent results
(if they are implemented by hashing) so it would be good to get in a few
buildfarm cycles and let that settle out before we start changing the
answers.
I do have some trivial nitpicks about 0001:
# rules cannot run concurrently with any test that creates a view
-test: rules psql_crosstab amutils
+test: rules psql_crosstab amutils tsrf
Although tsrf.sql doesn't currently need to create any views, it doesn't
seem like a great idea to assume that it never will. Maybe add this
after misc_functions in the previous parallel group, instead?
+-- it's weird to GROUP BYs that increase the number of results
"it's weird to have ..."
+-- nonsensically that seems to be allowed
+UPDATE fewmore SET data = generate_series(4,9);
"nonsense that seems to be allowed..."
+-- SRFs are now allowed in RETURNING
+INSERT INTO fewmore VALUES(1) RETURNING generate_series(1,3);
s/now/not/, apparently
More to come later, but 0001 is pushable with these fixes.
