bootstrapping DB for each user

[degaurab]

Step taken right now:

• Create database for user:

   queryString := fmt.Sprintf("CREATE DATABASE %s", dbname)
  

• Create user:

  queryString = fmt.Sprintf("CREATE USER %s with encrypted password '%s'", n.UserName, n.Password)
  
  

• Grant privileges to user:

  queryString = fmt.Sprintf(	"GRANT ALL PRIVILEGES ON DATABASE %s TO %s", n.DBName, n.UserName)
  
  

But I am guessing this are not sufficent enough to create isolation in shared DB.
Would be nice to get additional bootstrapping details.
