These values are being read by various test clauses in the tests below. In the noWhereClause test, I test reading all of them back and confirm we read something. I tried to specify the salt column, but it turns out tricky to get the value into the query. Can I do it in the next CL? I think the test coverage should be sufficient to test that the end behavior is correct, and the salt column is suppose to be transparent to the user.
