Tom,

There are no FK's or triggers on this or any of the tables in our 
warehouse schema.  Also I should have mentioned that this update will 
produce 0 rows as these values do not exist in this table.  We have a 
dimension table named d_servlet that holds servlet names and id's.  
This  table is shared amongst several fact tables including the one in 
question.  This update was to ensure that the changes in the d_servlet 
table would be reflected in f_commerce_impressions.  It turns out that 
the values did not exist in the table.

Here is output from the /usr/local/pgsql/data/servlerlog when this fails:
