postgresql: permission denied for relation

Question

I'm building a project using postgresql and java (NetBeans).

When I try to execute a simple query (select * from costumer) I get an error, telling me that "permission denied for relation costumer".

When I searched for an answer, all I found was about granting user privileges, so I went into pgAdmin and wrote "grant all privileges on database dirty to henrik;" . That didn't change anything - and that's why I'm making a new post..

The complete error message output of the program:

The java program is really simple - it looks like this:

package sletdendog;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;

public class SletDenDog {

private static Connection connection = null;
private static PreparedStatement statement = null;
private static ResultSet result = null;
private static ResultSetMetaData meta = null;

public static void main(String[] args) {

    try{
        System.out.println("1");
        connection = DriverManager.getConnection("jdbc:postgresql://localhost/dirty", "henrik", "hokus pokus");
        System.out.println("2");
        statement = connection.prepareStatement("select * from costumer;");
        System.out.println("3");
        result = statement.executeQuery();
        System.out.println("4");
        meta = result.getMetaData();
        System.out.println("5");
        for (int i = 1; i <= meta.getColumnCount(); i++) {
            System.out.println(meta.getColumnName(i));
        }

    } catch (SQLException ex){
        Logger lgr = Logger.getLogger(SletDenDog.class.getName());
        lgr.log(Level.SEVERE, ex.getMessage(), ex);
    } finally {
        try{
            if(connection != null){
                connection.close();
            }
            if(statement != null){
                statement.close();
            }
            if(result != null){
                result.close();
            }
        } catch(SQLException ex){

            System.out.println("Something wasn't closed...");

        }
    }   
}

Privileges on the database are not enough.
You also need at least the USAGE privilege for relevant schema and the SELECT privilege for the table.
