Can't connect to PostgreSql via GORM in Golang. What can be wrong?

Question

PostgreSQL

What could be the reason that there is no access to the PostgreSQL database through GORM, but there is in PgAdmin. The settings are the same. Antivirus, firewall turned off. GORM pumped over a new one.

import(
        	//"github.com/jinzhu/gorm/dialects/postgres"
          "github.com/jinzhu/gorm"
          _ "github.com/lib/pq"
       )

The connection code

db, err := gorm.Open("postgres", "host=localhost:5432  user=postgres password=RomanRakzin dbname=MyDB  sslmode=disable")  
        if err != nil {
           log.Println("Ошибка подключения к базе данных......") 
        }

And I tried without specifying `host=localhost:5432` and just `host=localhost`.
There is a database, a user with such a password, too. Everything works in PgAdmin, but not here.
