-Fix postgresql-socket on Lispworks and CMUCL so that the
-socket stream uses a consistent element-type.
+TESTS TO ADD
+* Test that ":db-kind :key" adds an index for that key. This is complicated by
+ different backends showing autogenerated primary key in different ways.
+* :db-constraint tests
+* Number and Char field types
+* symbol slot
+* generalized-boolean slot
+* tests for db-reader and db-writer
+OPTIMIZATIONS
+
+* Revisit result-type list creation, perhaps caching
+* Rework LIST-ATTRIBUTE-TYPES and LIST-INDEXES such that they exhibit their
+ current behaviours using single database queries.
+* Possible use of cached attribute type information for operations which
+ insert/update records as mentioned in the CommonSQL user guide.
+* Extend caching of generated SQL strings to more complex expressions which
+ are likely to be repeatedly executed many times.
+
+POSSIBLE EXTENSIONS
+
+* improve large object api and extend to databases beyond postgresql
+* add support for prepared statements
+
+RACE CONDITIONS
+* sql/databases.lisp: *connected-databases* is shared globally but not modified in a threadsafe manner.
