Add a link section to the docs
Default :on-delete and :on-update in !foreign to :restrict
Fix bizarre row/col symbol name confusion in table.lisp

I'm really not sure where this came from.
Use different package names for internal ieee-floats and trivial-utf-8

This way they won't clash with the regular distribution of those packages
Simplify the check for whether cl-postgres glue is to be loaded

Apparently, ASDF2's asdf:operation-done-p returns true in situations where
I wouldn't expect it to. This was causing the glue to be loaded twice.
Slightly more refined check for when to load simple-date glue
Add support for PostGIS operators
added :not-null operator (it was already used in some examples in the doc)
trying a different approach than the target-class hack in build-dao-methods

(we just evaluate the code that defines methods; since it happens at compile
time it shouldn't be a big deal.  this fix was suggested by Marijn)
Added FOR UPDATE/SHARE support to S-SQL

FOR UPDATE/SHARE can be used with the SELECT statement in order to lock the
selected rows against concurrent updates.

The syntax is similar to :limit and :order-by, and supports OF and NOWAIT.

Example:
(:for-update (:select :* :from 'mytable) :of 'mytable :nowait)

Documentation:
http://developer.postgresql.org/pgdocs/postgres/sql-select.html
Updated S-SQL reference manual.
Added !unique deftable constraint and implemented deferrability for it and !foreign.
Implemented :set-constraints s-sql operator.
Allow !foreign to explicitly reference the primary key of the foreign table.
First argument to !unique need not be a list.
Updated docs to describe !unique and the new !foreign functionality.
Document new s-sql operator :set-constraints
Adds constraint to database-error condition.
Reduce impact of patch 9b69c308b393f, add docs
Fix some oversights in previous patch
