Hi,

And here I begin to have a doubt - the sea polygons are tagged
natural=water_sea. My assumption was that these would be ignored in
rendering because no such tag is understood. But as it's a "natural"
tag, won't it actually be considered a polygon and stored in the DB
anyway? If so, it must be the culprit. What do you think?
It will certainly be stored in the DB because osm2pgsql does not know
about rendering rules. Plus, there it at least one query in the standard
rendering rules that will actually *retrieve* such a polygon and return
it to the Mapnik library for processing (where it will then be discarded):
<Layer name="text-poly" status="on" srs="&osm2pgsql_projection;">
<StyleName>text</StyleName>
<Datasource>
<Parameter name="table">
(select
way,aeroway,shop,access,amenity,leisure,landuse,man_made,"natural",place,tourism,NULL
as ele,name,ref,military,waterway,historic,'no'::text as point
from &prefix;_polygon
where amenity is not null
[...]
or "natural" is not null
[...]
) as text
</Parameter>
&datasource-settings;
</Datasource>
</Layer>
You could try commenting that layer out to see if that improves the
situation.
Bye
Frederik
