Hey @MaximeMRF! 👋🏻

Thanks for your PR! I have added a few remarks about your changes.

If we merge this, we need to ensure serialization works correctly with BigInt during HTTP response and add some notes in the Lucid documentation to correctly cast the value depending on the DBMS used.

Hello @RomainLanz

Some tests doesn't pass but I think it's not my fault.

[RomainLanz]

Should we also allow to cast numbers to bigint?

[MaximeMRF]

Yeah, it's a good idea

Hey @RomainLanz, I've added the cast of a number to bigint type, it is ok now ?
