You need to provide enough information for somebody else to reproduce
the problem. Please read
http://www.postgresql.org/docs/8.4/static/bug-reporting.html
The usual way to report this type of issue is to create a SQL script
that will reproduce it starting from an empty database. You can start
from a pg_dump script and then try to trim out anything that's
confidential or irrelevant, and/or reduce the amount of data, if the
script seems too large to mail to the list.
