What postgres data type does the avg_r_tax_val_0906 column use?
Looking in the Mapnik postgis plugin source, the numeric2string function
sticks out as possibly being relevant. You could try adding some debug
in there.
What machine is this running on, an x86 cpu or something else? Is the DB
on the same machine as Mapnik or a remote connection?
