Without "user-level docs" (now I understand that the term means all SGML docs for you), it is very hard to find a visible characteristics/behavior of the patch. CREATE/DROP/ALTER STATISTICS just defines a user interface, and does not help how it affects to the planning. The READMEs do not help either.
In this case reviewing your code is something like reviewing a program which has no specification.
That's the reason why I said before below, but it was never seriously considered.
I would likely have said this myself but didn't even get that far.
Your contribution was useful and went further than anybody else's review, so thank you.
