Thanks Martijn, I checked the database logs after well behaving queries
sent by other clients and saw that there is not much wrong in the query
sent by nik2img-Mapnin chain. My database is now in 32635 and
st_transform is not needed. Therefore setSRID('BOX3D(392527.9999999671
6673681.999999999,500000 6676265.999999509)'::box3d,32635) is otherwise
OK, but for some reason it does not take the easting parameters as I
give those. MaxX parameter 392528 is used as MinX (after going through
some rather accurate calculation) and static value 500000 is used as
MaxX. For me this looks like a bug either in the script or in Mapnik
but perhaps I am giving the parameters wrongly. According to nik2img
help -r 389725,6673682,392528,6676266 should be correct.
Should I try running Mapnik-WMS instead of nik2img? I would prefer using
nik2img because I just want to get Mapnik maps which I could
georeference simply and accurately to be used in GIS programs. And I
have already both Mapserver and Geoserver WMS running on this computer.
But I can tolerate having a third WMS if that is the way to go. Most
fresh Mapnik Windows version seems to be 0.5.1, is it enough for running
WMS service?
