# cat datasource-settings.xml.inc
<!--

<Parameter name="type">postgis</Parameter>

<Parameter name="host">lurien.paulla.asso.fr</Parameter>
<!-- Parameter name="port">%(port)s</Parameter -->
<Parameter name="user">mapnik</Parameter>
<Parameter name="dbname">mapnik_cc</Parameter>
<!-- this should be 'false' if you are manually providing the 'extent'

<Parameter name="estimate_extent">true</Parameter>
<!-- manually provided extent in epsg 900913 for whole globe -->
<!-- providing this speeds up Mapnik database queries -->
<!-- Parameter name="extent">%(extent)s</Parameter -->


I'll try your settings...
