Bug description

I have a model with a column of type DateTime @db.timestamptz(6) as primary key. Microsecond precision is essential in this application. I try to create multiple rows with the same millisecond but different microseconds and Prisma throws a UniqueViolationError.

How to reproduce

TODO: complete MVE

With this model:

model MetadataMarkers {
  metadataID   BigInt
  timestamp     DateTime              @db.Timestamptz(6)
  marker  Json
  @@id([metadataID, timestamp])

Expected behavior

All the rows are added successfully.
