 For Postgres we use `enum type name + title cased` value to generate the const variable name.
 For MySQL we use `table name + column name + title cased value` to generate the const variable name.

+Note: If your enum holds a value we cannot parse correctly due, to non-alphabet characters for example,

 the value randomizer in the test suite does not know how to generate valid enum values. You will
 still be able to use your generated library, and it will still work as expected, but the only way
