-GENERAL 
+TESTS TO ADD
 
-* test on mcl. SCL no longer affordable to individuals;
-* implement remaining functions for CLSQL AODBC backend;
-* port Oracle and ODBC 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.
+* Test bigint type
+* :db-constraint tests
+* test *db-auto-sync* 
+* for-each-row macro
+* universal-time
