From the release 2.3 onwards, you can decide whether PostalCode will validate formatting or not, and we will start supporting regexes for both cases.

Check the docs for the upcoming release:

https://github.com/Respect/Validation/blob/2.3/docs/rules/PostalCode.md

I won't accept your PR because it is targeted for an older PostalCode rule, but I added a test case for your scenario.

Thanks for reporting this 🐼
