v11 with the examples work as a separate patch over v10 to be squashed.

Tried to be consistent on "Title Case" within headers other than a few
where the all-caps operator really made the most sense.
Got NULL for SQL null literals throughout and Null for psql display of the
same.
Removed abbreviations in titles generally. Re-worked a couple of the more
complex ones.

Decided to leave my agent instructions in place (xml-styled comment). The
flow actually worked pretty well, though it's nuanced enough to be wary of
false-negatives. Hopefully I got them all.
