Please, proof-read it, English isn't my native language.
As usual, I had to make choices about what to present here. If your favorite feature isn't here, please add it, or tell me about it :)
A couple points
1) CHECK ... NO INHERIT should get its own heading. It isn't really a matter of a NOT VALID check constraint.
2) I don't know how these are getting ranked but the SECURITY BARRIER bit might do better as a major feature. It has the potential to be a total game changer in the way multi-tenant applications are developed and viewed.
