ok, I downloaded elephant, installed that, then instaleed postgre, the software was running nice, but next day, I don't know why (probably not for elephant) I couldn't turn computer on, so I just uninstalled everything automaticly, now elephant wasn't uninstalled, but postgre was, and I can't install postgre again now, it says "the password is too short or not complex enought". I try every possible password and username, but that doesn't help. What could be problem? I deleted postgre folder, I can't find username of postgre, so... I don't know how to install it again. Maybe you know how to do that. Thanks,
