Migration continually recreated despite schema not changing - dbgenerated nextval

Bug description

Schema is not changed but migration is continually recreated for a dbgenerated id:

id String @id @default(dbgenerated("'policy_'|| nextval('policy_seq')"))

I have tried various syntaxes to no avail. Postgres shows it as: id text COLLATE pg_catalog."default" NOT NULL DEFAULT ('policy_'::text || nextval('policy_seq'::regclass)),

How to reproduce

Add to schema with Postgres provider:  id String @id @default(dbgenerated("'policy_'|| nextval('policy_seq')"))

Expected behavior

Create an original migration but should not create any more subsequent migrations after the original one. Unfortunately it continually creates a new migration on prisma migrate dev

Prisma information

model Policy {
  id                     String                   @id @default(dbgenerated("'policy_'|| nextval('policy_seq')"))
  name               String                   @unique

  @@map("policy")
}

Environment & setup

• OS: MacOS
• Database: PostgreSQL
• Node.js version: 18

Prisma Version

4.2.0

That did actually fix the issue, thanks!

Thanks. That is fortunately pretty close to what Postgres shows itself 👍
