 TESTS TO ADD
 
-* CACHE-TABLE-QUERIES
-* Test that ":db-kind :key" adds an index for that key. This is complicated by different
-  backends showing autogenerated primary key in different ways.
-* Large object testing
-* Test bigint type
+* Test that ":db-kind :key" adds an index for that key. This is complicated by

 * :db-constraint tests
-* test *db-auto-sync* 
-* test SELECT caching

-COMMONSQL SPEC
-
-* Missing: 
-
-  UPDATE-OBJECT-JOINS 
-
-* Incompatible 
-
- >> The functional sql interface 
-  
-    SELECT 
-      o keyword arg :refresh should function as advertised 
-
- >> Symbolic SQL syntax 
-
-      o Complete sql expressions (see operations.lisp)
-
-         nvl (Oracle specific) 
-         userenv (Oracle specific) 
-        minus (Oracle specific: does the same as EXCEPT) 
-        || 
-
-      o variables (e.g., table identifiers) should be instantiated at runtime 
+* 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
+ 
+* 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
 
-* port Oracle backend to UFFI
-* large object support 
+* improve large object api and extend to databases beyond postgresql 
 * add support for prepared statements

-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
