Handle range-typed columns #24
Description
As requested by @kiwiroy, PostgreSQL has among other types int8range. For this library to handle that, it would need a suitable GraphQL type to map it to. I believe this would need to be both an input and a type, with something like these fields:
- (Integer or Float or DateTime) lower
- (Integer or Float or DateTime) upper
- Boolean lowerInclusive
- Boolean upperInclusive
