    24 Since version 0.9, Trac supports both [http://sqlite.org/ SQLite] and 
    25 [http://www.postgresql.org/ PostgreSQL] as database backends.  The default 
    26 is to use SQLite, which is probably sufficient for most projects. The database file 
    27 is then stored in the environment directory, and can easily be 
    28 [wiki:TracBackup backed up] together with the rest of the environment. 
     24Since version 0.9, Trac supports both [http://sqlite.org/ SQLite], 
     25[http://www.postgresql.org/ PostgreSQL] and [http://mysql.com/ MySQL] as

    35 If you want to use PostgreSQL instead, you'll have to use a different 
    36 connection string. For example, to connect to a database on the same 
    37 machine called `trac`, that allows access to the user `johndoe` with 
    38 the password `letmein`, use:

    4849Note that with PostgreSQL you will have to create the database before running 
    4950`trac-admin initenv`. 
     51 
     52And make sure PostgreSQl DB name is "trac". What worked for me: 
     53And didn't work uppercase trac-user-name 
     54{{{ 
     55sudo su - postgres -c createdb trac 
     56sudo su - postgres -c psql trac 
     57CREATE USER trac-user-name WITH PASSWORD 'trac-pass-name'; 
     58}}}

     60== Source Code Repository == 
     61 
     62You'll first have to provide the ''type'' of your repository (e.g. `svn` for Subversion, 
     63which is the default), then the ''path'' where the repository is located. 
     64 
     65If you don't want to use Trac with a source code repository, simply leave the ''path'' empty 
     66(the ''type'' information doesn't matter, then). 
     67 
     68For some systems, it is possible to specify not only the path to the repository, 
     69but also a ''scope'' within the repository. Trac will then only show information 
     70related to the files and changesets below that scope. The Subversion backend for 
     71Trac supports this; for other types, check the corresponding plugin's documentation. 
     72 
     73Example of a configuration for a Subversion repository: 
     74{{{ 
     75[trac] 
     76repository_type = svn 
     77repository_dir = /path/to/your/repository 
     78}}} 
     79 
     80The configuration for a scoped Subversion repository would be: 
     81{{{ 
     82[trac] 
     83repository_type = svn 
     84repository_dir = /path/to/your/repository/scope/within/repos 
     85}}}

    … …  
    67103 * `wiki-macros` - Environment-specific [wiki:WikiMacros Wiki macros].

     105  '''Note: don't confuse a Trac environment directory with the source code repository directory. 
     106It happens that the above structure is loosely modelled after the Subversion repository directory  
     107structure, but they are not and ''must not'' be located at the same place.'''
