-Fix postgresql-socket on Lispworks and CMUCL so that the
-socket stream uses a consistent element-type.
+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.
+* Test bigint type
+* :db-constraint tests
+* test *db-auto-sync*
+* for-each-row macro
+* universal-time
+COMMONSQL INCOMPATIBILITY
+
+<<<<<<< .mine
+ o Complete sql expressions (see operations.lisp)
+
+ nvl (Oracle specific)
+ userenv (Oracle specific)
+ minus (Oracle specific: does the same as EXCEPT)
+ ||
+
+=======
+>>>>>>> .r9364
+ o variables (e.g., table identifiers) should be instantiated at runtime
+
+<<<<<<< .mine
+=======
+ >> The functional sql interface
+
+ SELECT
+ o keyword arg :refresh should function as advertised
+
+ >> Symbolic SQL syntax
+
+ 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.
+
+>>>>>>> .r9364
+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
+
+POSSIBLE EXTENSIONS
+
+* extend large object support to databases beyond postgresql, improve large object api
+* add support for prepared statements
+* port Oracle backend to UFFI
+
+
+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
+syntax: doesn't support the sql concatenation operator (||).
+
+SQLITE
+
+create-view: column-list parameter not supported
+syntax: doesn't support the sql SUBSTRING operator.
