There are over 20 million records in a self-referential database table, where one record may point to another record as a descendant. Because of a bug in application code, there was no limit on recursion. The max was supposed to be 4. A few outlier records have between 5 and 5000 descendants (there could be more. I manually found one chain of 5000. I need to find all the chains of 5+ and mark them for update/deletion. While the database is about 10GB, the recursive search is maxing out on diskspace and causing a failure (there was over over 100GB of workspace free) Is there any way to make a recursive query work, or will I have to use another means and just iterate over the entire dataset (either in postgres or an external service) -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
