If you have created another database names the same to your username, (it should be done with createdb) then you may command psql only. Im running the OpenNMS installer which 'configures PostgreSQL tables,users, and other miscellaneous settings. And it seems it gives -d option by default, psql postgres also works. So if you don't have another database named your username, you need to do psql -d postgres for psql command to work. In the command line tools the -U flag does this. Create a suitable user, or specify a different username to connect with. You have not created a PostgreSQL user by that name in your database. The first database is always created by the initdb command when the data storage area is initialized. By default PostgreSQL connects to the PostgreSQL user with the same name as the current unix user. By psql -help, when you didn't set options for database name (without -d option) it would be your username, if you didn't do -U, the database username would be your username too, etc.īut by initdb (to create the first database) command it doesn't have your username as any database name.
