 * 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
 * :db-constraint tests
 * test *db-auto-sync* 
-* test SELECT caching
 * for-each-row macro
 * universal-time 
+* owner phrases for postgresql and oracle backends
+* test of large table with large numbers of rows, greater than 2x the number of
+  rows (200) returned by the oracle backend at a time
+* test mixed case table identifiers and column identifiers
 
-COMMONSQL SPEC
-
-* 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 
-
+COMMONSQL INCOMPATIBILITY
 
+   o doesn't support CHAR and NUMBER types as shown on CREATE-TABLE reference page
+   o (string n) => VARCHAR(n) rather than CHAR(n)
+   o userenv (Oracle specific but deprecated in Oracle 9) 
+ 
 VARIANCES FROM COMMONSQL
 
-UPDATE-OBJECT-JOINS:
- Rather than simply reading the values for each
- object, to meet CommonSQL spec need to generate a single
- query to read values for all objects, up to max-len count.
+COMMIT,ROLLBACK,START-TRANSACTION: 
+ When COMMIT or ROLLBACK are called outside of WITH-TRANSACTION, an sql 
+ transaction must be explicitly started first with START-TRANSACTION. 
 
 OPTIMIZATIONS
  
-* Revisit result-type list creation,perhaps caching
+* Revisit result-type list creation, perhaps caching
 
 POSSIBLE EXTENSIONS
 
-* port Oracle backend to UFFI
-* large object support 
+* extend large object support to databases beyond postgresql, improve large object api
 * add support for prepared statements
+* port Oracle backend to UFFI
