The problem is, most likely, on updating the indexes. Heap inserts should always take more or less the same time, but index insertion requires walking down the index struct for each insert, and the path to walk gets larger the more data you have. Postgres does not have bulk index insert, which could perhaps get you a huge performance improvement. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
