 ## Known issues
 
 * nil/NULL values are not completely supported, since many databases require `IS NULL`, or `IS NOT NULL`, you can use the null_type here, but it will only accept `nil`, and it will possibly not support what you're trying to do. YMMV.
 * Date/Datetime are not validated for their format, it is expected that you will pass the correct format.
+* Casting values with colons like postgres is currently not supported: `SELECT '100'::integer;` etc.
 
 
 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
