- >> Initialisation and connection 
-
-    CONNECT 
-     o should accept string as connection spec 
-
-    DISCONNECT
-     o should accept string as connection spec 
-
-    INITIALIZE-DATABASE-TYPE
-     o should initialise appropriate backend 
-
-    STATUS 
-     o what is the behaviour in CommonSQL (esp :full parameter)? 
-
-
- >> The functional sql interface 
-  
-    SELECT 
-      o should accept keyword arg :refresh and call INSTANCE-REFRESHED
-      o should return (values result-list field-names)

-NOTES ABOUT THE BACKENDS
-
-MYSQL 
-
-drop-index:   requires a table to be specified with the :from keyword parameter
-transactions: don't seem to work  
-views:        mysql does not support views  
-queries:      nested subqueries do not seem to work 
-
-SQLITE 
-
-create-view: column-list parameter not supported 
+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
