-GENERAL 
+TESTS TO ADD
 
-* port Oracle backend to UFFI.
+* 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

+OPTIMIZATIONS
+
+* Revisit result-type list creation,perhaps caching
+* Use an inner join for :target-slot in SELECTS rather than multiple
+  queries. For example, in the test suite:
+    SELECT address.addressid,address.street_number,... FROM address
+      INNER JOIN employee_address ON employe_address.address_id=address.address_id
+      AND emplid=<id>
+
+POSSIBLE EXTENSIONS
+
+* port Oracle backend to UFFI
+* large object support 
+* add support for prepared statements
