- Fix formatting on giant postgres query
- Invert the section that looks for unique constraints to look for a
constraint and join to the constraint_column_usage to be more in line
with the mysql query and also it makes a little bit more sense.
- Add more checks to ensure the schema is being enforced in the postgres
side of things as several pieces in the unique checks were missing it
which would lead to false positives.
- Fix#77 for postgres
