Re: Out of memory error when doing an update with IN clause

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:
