Hi all! I have installed Mandrake 9.0. and postgresql is installed automatically. When I start postgresql by the command: postmaster -i have a error message: The server must be started under an unprivileged user id to prevent a possible system security compromise. See the documentation for more information on how to properly start the server. With Mandrake 8.0, I do nothing to config postgresql. So what I can do to config it now? Please help me! thank you very much. ******************************************************* Tran Anh Tu Vien CNTT - DHQG Ha Noi Phone: 047680417-25 Email trantu@xxxxxxxxxx *******************************************************
