error: The prefix db is invalid

Description and expected behavior
Hi, i have a model in the schema that looks like

model alembic_version {
  version_num String @id(map: "alembic_version_pkc") @db.VarChar(32)
}

This throws an error when running zenstack generate

Error: Prisma schema validation - (get-dmmf wasm)
Error code: P1012
error: The prefix db is invalid. It must be equal to the name of an existing datasource e.g. postgresql. Did you mean to use postgresql.VarChar?
  -->  schema.prisma:298
   |
297 | model alembic_version {
298 |     version_num String @id(map: "alembic_version_pkc") @db.VarChar(32)
   |

Validation Error Count: 1
[Context: getDmmf]

If i change to

model alembic_version {
  version_num String @id(map: "alembic_version_pkc") @postgresql.VarChar(32)
}

Then in vscode i get Could not resolve reference to Attribute named '@postgresql.VarChar'.zmodel(linking-error)
and when trying to generate i get

Validation errors:
line 330: Could not resolve reference to Attribute named '@postgresql.VarChar'. [@postgresql.VarChar]
error Command failed with exit code 1.

The second option should be the right one since is what prisma expects (it's generated by prisma db pull)

Any ideas?

Environment (please complete the following information):

• "zenstack": "1.12.3"
• "prisma": "^5.12.1",
• Database type: Postgresql
