`Gist` index not supported on prisma schema

Bug description

Hello

I’m introspecting my database and this is the schema that is being generated when I use the prisma cli and run npx prisma db pull.

model appointment {
  account_id String                   @default(dbgenerated("(current_setting('app.account'::text))::uuid")) @db.Uuid
  id         String                   @default(dbgenerated("gen_random_uuid()")) @db.Uuid
  date       Unsupported("tstzrange")
  patient_id String                   @db.Uuid
  is_paid    Boolean                  @default(false)
  is_active  Boolean                  @default(true)
  created_at DateTime                 @default(now()) @db.Timestamptz(6)
  patient    patient                  @relation(fields: [account_id, patient_id], references: [account_id, id], onDelete: NoAction, onUpdate: NoAction, map: "FK_Appointment_patient_id__Patient_id")
  account    account                  @relation(fields: [account_id], references: [id], onDelete: NoAction, onUpdate: NoAction)

  @@id([account_id, id], map: "PK_Appointment_account_id_id")
  @@index([account_id, date], map: "appointment_account_id_date_excl", type: Gist)
}

I get the following error once I try to generate the client by running npx prisma generate.

This is the error.

Error: Schema validation error - Error (query-engine-node-api library)
Error code: P1012
error: Error parsing attribute "@@index": The Gist index field type `Uuid` has no default operator class.

I thought Gist indexes where supported as stated on https://www.prisma.io/docs/concepts/components/prisma-schema/indexes#index-configuration

How to reproduce

Try to generate the prisma client based from this schema, use the cli npx prisma generate.

model appointment {
  account_id String                   @default(dbgenerated("(current_setting('app.account'::text))::uuid")) @db.Uuid
  id         String                   @default(dbgenerated("gen_random_uuid()")) @db.Uuid
  date       Unsupported("tstzrange")
  patient_id String                   @db.Uuid
  is_paid    Boolean                  @default(false)
  is_active  Boolean                  @default(true)
  created_at DateTime                 @default(now()) @db.Timestamptz(6)
  patient    patient                  @relation(fields: [account_id, patient_id], references: [account_id, id], onDelete: NoAction, onUpdate: NoAction, map: "FK_Appointment_patient_id__Patient_id")
  account    account                  @relation(fields: [account_id], references: [id], onDelete: NoAction, onUpdate: NoAction)

  @@id([account_id, id], map: "PK_Appointment_account_id_id")
  @@index([account_id, date], map: "appointment_account_id_date_excl", type: Gist)
}

Expected behavior

The prisma client is generated with no errors.

Internal: Next step is to try to reproduce locally what @gmwill934 is seeing, and then figure out what is going on with that ops class.
