Yes, something like that.

The SRS in each of your layer descriptions that access PostGIS must be 
changed to proj=latlon. The SRS of your map will remain whatever you 
want the map to be produced in. Be aware that using an extent that is 
larger than the map SRS allows might break things, so if you want to 
produce maps in EPGS:900913 (normal tiles) then you should only specify 
+/- 85 in your extent, not +/- 90.

Bye
Frederik
