Add support for 64-bit integers

Problem

Lots of database support 64-bit integers. We don’t support them yet because not all databases support them.

Possible Solution

In the databases that support 64-bit integers, we add datasource-specific attributes to define 64-bit types.

Original Issue

Prisma1 did not support Long integers (64-Bit). Will Prisma2 support Long (64-Bit) in parallel to Int (32-Bit)?

Hey @nickreynke!

Prisma 2 doesn’t currently support 64bit integers, however we’re planning to add support for them depending on the database using Type Definitions.

While we haven’t implemented them yet

datasource pg {
  provider = "postgresql"
}

type Long Int @pg.bigint

model User {
  bignum Long
}

We’re also looking for feedback on the syntax, so if you have any thoughts there let me know. Would this address your issue?

Is there any workaround to use bigint in js?
