[CockroachDb] Investigate Partial Indices

See original GitHub issue

It seems like some partial indexes e.g. where x =5 do not seem to be correctly filtered out when introspected on CockroachDb vs on Postgres.

Example: https://github.com/prisma/database-schema-examples/blob/8cea37d834f3effd6aad53e98c5bc865b4d85335/postgres/canvas-lms/schema.sql#L13216

(Disregard if unrelated)

The current implementation of MongoDB uniques don’t behave the same as SQL with nullability. We’re currently trying to decide how to deal with this (needs a discussion with migrations team still). One suggestion was to actually support partial indices in Prisma: https://github.com/prisma/prisma-engines/issues/2361

Cockroach Cloud Serverless, which is showing this behavior, is currently running on a specific version that does not include the fix that Matthias mentioned. Next week it will be updated to a newer version, and we expect the problem to magically go away when that happens.
