Oh, I missed that patch, thanks for pointing it out!

Just one small style comment: in the documentation, table constraints are
listed in the order CHECK, NOT NULL, UNIQUE, PRIMARY KEY, etc. So it might
be better to follow that same order in the code for consistency in all
three places mentioned above.
