I have a remote database which I can connect to using psql command line tool as well as PgAdmin4. But I would really like to use DataGrip. But whenever I try to connect, it gives me fatal: password authentication failed and prompts me for another password. I raised an issue in DataGrip and I was told there is an issue in my database configuration.

Here is my pg_hba.conf:
```
# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            scram-sha-256
# IPv4 connections from internet
host    database    user          0.0.0.0/0               scram-sha-256
host    database    user          0.0.0.0/0               md5
host    database    user          0.0.0.0/0               password
# IPv6 local connections:
host    all             all             ::1/128                 scram-sha-256
# IPv6 connections from internet:
host    database    user          ::0/0                   scram-sha-256
host    database    user          ::0/0                   md5
host    database    user          ::0/0                   password
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all
```

Since I know a Java and I know Idea uses java, so I wrote this small snippet to try to connect to my server using JDBC:
```java
public class Test {
     public static void main(String[] args) throws SQLException {
        Connection connection = DriverManager.getConnection(
            "jdbc:postgresql://url/database",
            "user",
            "password"
        );

        try (connection) {
             Statement statement = connection.createStatement();
             statement.execute("select version()");
        }
    }
}
```
And it failed with the same error
