[PostgreSQL] Cannot create or update row with large Decimal value within `numeric` range

Bug description

I have a schema with a model which has a Decimal value. When I try to create or update an entry passing as value a large number such as Prisma.Decimal('93431006234343600001'), the operation fails with the following error

  Error parsing GraphQL query: query parse error: Parse error at 3:12
number too large to fit in target type

How to reproduce

I have created a reproduction repo which can be found at https://github.com/codazzo/prisma-decimal-precision-repro

Expected behavior

My understanding is that with a Decimal type I should be able to run

  await prisma.entry.create({
    data: {
      value: new Prisma.Decimal('93431006234343600001')
    }
  })

Note that I am able to find any entities that hold large values from the DB. If the value is 93431006234343600001 in the DB, I can successfully call prisma.entry.findUnique() and get the value back.

Do we have any update on this or a progress update here? A project I am working on is blocked by this.

I’m hitting this problem too, and with BigInt column type.

Please add some basic test cases for this and fix it asap, basically all big number support is broken.
