How to map data types in MS Visio 2010?

Question

PostgreSQL

Using ODBC, PostgreSQL (psqlodbc) imported all the necessary tables from the PostgreSQL database into a Visio document. When importing, no errors occur, everything is OK. But after the import, the field types in the imported tables do not match the field types of the tables that are in the PostgreSQL database. An example is below.
The role table , which in the PostgreSQL DB is:

CREATE TABLE "role" (
    id serial NOT NULL,
    "name" varchar(30) NOT NULL,
    "count" integer,
    description text,
    created_at integer,
    updated_at integer,
)

The role table in Visio after importing from the PostgreSQL database:

As you can see, the varchar(30) type of the name field in Visio has become longvarbinary , although the varchar type is present in Visio . The same problem with the description field , etc.
Where is the correct type mapping configured in Visio? So that when imported, varchar is varchar, and not something else.
Thank you!
