https://www.notion.so/prismaio/Proposal-Scalar-List-Defaults-94d0891a3355475999f10b270e2a311a

What needs to happen is TBD.

Incomplete notes:

• Remove autoincrement()
• Auto complete empty list by default
• No functions in auto completions except dbgenerated

[Jolg42]

So auto completions for this schema for @default(|) (from prisma/prisma-engines#2946)

        datasource db {
          provider = "postgresql"
          url      = "env(TEST_DATABASE_URL)"
        }
        model defaults {
          id                String     @id
          text_empty        String[]   @default()
          text              String[]   @default()
          text_c_escape     String[]   @default()
          colors            color[]    @default()
          int_defaults      Int[]      @default()
          float_defaults    Float[]    @default()
          bool_defaults     Boolean[]  @default()
          datetime_defaults DateTime[] @default() @db.Timestamptz
        }
        enum color {
          RED
          GREEN
          BLUE
        }

should be
[] or dbgenerated() (but not [dbgenerated(...)])
