postgis with itemnquery

[Richard Greenwood]

My query arguments seem to be getting cast to numeric values when I
use postgis (but not when I use shape files). For example:
   qitem=(mapnum=0009)
seems to be interpreted as
  mapnum=9
I have tried escaping the value with no success. The "mapnum" column
is a character field.

So my questions:
1. Does anyone have suggestions for escaping the value, or
constructing the query differently?
2. How can I log the actual query that is constructed and passed to postgresql?
3. What .c file is used to process itemnquery for postgis?

Thanks,
Rich
