UseIdentityAlwaysColumns for custom types

[akazik]

Hi,

we use a custom type instead of long as a key.

Example:

// ID
public readonly partial record struct AddressId {
  public AddressId(long raw) {
    Raw = raw;
  }
  public long Raw { get; }
}

// Converter
public class AddressIdValueConverter : ValueConverter<AddressId, long> {
  public AddressIdValueConverter()
    : base(
      v => v.Raw,
      v => new(v)
    ) { }
}

// Registering it
   configurationBuilder
      .Properties<AddressId>()
      .HaveConversion<AddressIdValueConverter>();

// The file is actually generated out of a name and type
// and contains a lot more (like json conversion, model binder, tostring)

Which works like a charm, except that

    modelBuilder.UseIdentityAlwaysColumns();

has no effect.

Though it can be set on a per property basis:

        entity.Property(x => x.AddressId).UseIdentityAlwaysColumn();

Used versions:
Npgsql (8.0.6)
Npgsql.EntityFrameworkCore.PostgreSQL (8.0.11)
in a .net 8 project with EF 8.*

It would be great if UseIdentityAlwaysColumns could also work in this case.
