database connection error

Hello.
I am trying to connect to the PostgresSQL database I have created. I am trying to use Table Input step. I have created a New Connection which looks something like this:

Host Name: http://99.99.99.99/phppgadmin
Database Name: Name
Port Number: 5432
User Name: UserName
Password: ******

When I click "Test" button I get an error:

Error connecting to database: (using class org.postgresql.Driver)
No suitable driver found for jdbc:postgresql://http://31.31.73.61/phppgadmin:5432/mare

I tried to google something about this problem but I did not find any solution.
Can someone help me please?

Thank you
