Hello people, I was trying to install dspace on my computer and it required postgresql as a prerequisite. Since I am using Ubuntu so i just downloaded and installed it using synaptic package manager. For the installation of dspace i was supposed to exeucte the following command.. createuser -U postgres -d -A -P dspace but whenever i execute it, it asks for password for the new role and then after giving the password..it says..
createuser: could not connect to database postgres: FATAL: password authentication failed for user "postgres"
when i posted the question on dspace mailing list..one of the guy replied me with this solution.. createuser -h localhost -U postgres -d -A -P dspace but he said that to execute the above command i must know the password for the user postgres.. on running this command at the end i was prompted to the enter the password for the user postgres but i don't know the password..I think this user was created as default at the time postgresql was installed..then there must be a default password ... Please help me with this problem..
