Summary: SQL integer is not hashable

Initial Comment:
I'm unable to use a numeric value as the key in a dictioary.
This is the error message:

  Traceback (most recent call last):
  File "Cerebrum/tests/SQLDriverTestCase.py", line 30, in 
testSQLIntHashable
      hash[value] = 1
  TypeError: unhashable instance

This is a fragment of the test code that fails:

  self.db.execute("CREATE TABLE test_db_dict (value 
NUMERIC(6,0))")
  self.db.execute("INSERT INTO test_db_dict (value) 
VALUES (1)")
  value = self.db.query_1("SELECT max(value) FROM 
test_db_dict")
  hash = {}
  hash[value] = 1
