verify Postgresql change to casing

Postgresql is awful.

Postgresql will case-fold your column/table names to all lower
case unless your create scripts have them captured in quotes. The
problem here is that even if you have them captured in quotes,
your queries will return no results if you do not also capture
the column/table names in quotes.

This causes headaches when third party libraries are used to
interact with the database; these libraries do not know that
you really wanted to have case-sensitive table/column names, so
they do not quote your table/column names and return no results.

I ended up simply normalizing all the table/column names to lower
case for postgresql and am enforcing the test author to properly
serialize their data to json, which is case SENSITIVE. Example:

`obj.randomNumber` will fail if your orm returns a result set of
`{"id": 123, "randomnumber" 5015}` and you do not manually
serialize that data.
