- >> The functional sql interface 
-  
-    SELECT 
-      o keyword arg :refresh should function as advertised 
-      o should return (values result-list field-names)
-      o should coerce values returned as strings to appropriate lisp type
-
-    QUERY 
-      o should coerce values returned as strings to appropriate lisp type
-	for SQLite backend
-
- >> The object-oriented sql interface
-
-    DEF-VIEW-CLASS
-      o get :target-slot working 
-      o implement :retrieval :immediate 
-
-    DO-QUERY,MAP-QUERY,LOOP
-      o should work with object queries as well as functional ones 
-

- >> Symbolic SQL syntax

-NOTES ABOUT THE BACKENDS
-
-MYSQL 
-
-drop-index:   requires a table to be specified with the :from keyword parameter
-views:        mysql does not support views  
-queries:      nested subqueries are not supported
-
-SQLITE 
-
-create-view: column-list parameter not supported 
+* 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
