Looks pretty good.  A couple minor suggestions:

* Ports list entries for Windows should mention that Cygwin is needed;
as is, it gives the impression that we run natively.

* Query Language Features section should start out by saying that we
support nearly all of SQL92 entry level, plus numerous features from
SQL92 intermediate/full levels and SQL99.  That's needed context for
the details that the list then plunges into.  Would it be appropriate
to list the SQL92 entry level features we don't have?

* "Support for UNION and UNION ALL, INTERSECT and EXCEPT" implies that
we don't have INTERSECT ALL and EXCEPT ALL.  Rephrase, possibly as
"Support for UNION, INTERSECT and EXCEPT, including their ALL variants".

* The mention of full-text indexing probably belongs in the sub-bullet
about loadable extension functions, since it's not part of the standard
install.  Also, this sub-bullet should probably go more like "Loadable
extension functions include soundex etc etc", to make it clear this is
just some of 'em.
