This patch is particularly helpful in processing OpenStreetMap Data in PostGIS. OpenStreetMap is imported as a stream of 300-900 (depending on settings) gigabytes, that are needing a VACUUM after a COPY FREEZE. With this patch, the first and usually the last transforming query is performed much faster after initial load. I have read this patch and have no outstanding comments on it. Pavan Deolasee demonstrates the expected speed improvement. The new status of this patch is: Ready for Committer
