LTree column type doens worked with migration

[sentaniel]

Hello. I have next entity class

public class OrganizationModule
{
    public int Id { get; set; }
    public int OldSystemId { get; set; }
    public string Name { get; set; } = null!;
    public ModuleType Type { get; set; }
    public LTree Path { get; set; }
}

with this EntityConfig class

  public void Configure(EntityTypeBuilder<OrganizationModule> builder)
   {
       builder.HasKey(x => x.Id);
       
       builder.Property(x => x.Name).HasMaxLength(200).IsRequired();
       builder.Property(x => x.Path).HasColumnType("ltree");
       builder.HasIndex(treeItem => treeItem.Path).HasMethod("gist"); 
   }

It`s generated this migration

            migrationBuilder.AddColumn<string>(
                name: "Path",
                table: "OrganizationModules",
                type: "ltree",
                nullable: false,
                defaultValue: "");

            migrationBuilder.CreateIndex(
                name: "IX_OrganizationModules_Path",
                table: "OrganizationModules",
                column: "Path")
                .Annotation("Npgsql:IndexMethod", "gist");

But in db snapshot class we have this:

                    b.Property<string>("Path")
                        .IsRequired()
                        .HasColumnType("ltree");

and when I will try get any data. I have this error:
"Exception occurred: The 'LTree' property 'OrganizationModule.Path' could not be mapped to the
database type 'ltree' because the database provider does not support mapping 'LTree' properties to 'ltree' columns. Consider mapping to a different database type or converting the property value to a
type supported by the database using a value converter. See https://aka.ms/efcore-docs-value-converters for more information. Alternately, exclude the property from the model using the '[NotMapped]' attribute or by usi
ng 'EntityTypeBuilder.Ignore' in 'OnModelCreating'.
