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

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.
