                        |   | 72 | When running `createuser` you will be prompted for the password for the user 'tracuser'. This new user will not be a superuser, will not be allowed to create other databases and will not be allowed to create other roles. These privileges are not needed to run a trac instance. If no password is desired for the user, simply remove the `-P` and `-E` options from the `createuser` command.  Also note that the database should be created as UTF8. LATIN1 encoding causes errors trac's use of unicode in trac.  SQL_ASCII also seems to work.  |
