Hi Tom, Having been working with the PostGIS team to implement a custom analyze routine for R-Tree selectivity, we have a question regarding the new vacuum_delay_point() which is present in analyze.c. Is it the responsibility of the programmers to remember to do a vacuum_delay_point() before calling the fetch_func(), or would it be better to move the vacuum_delay_point() into std_fetch_func()? It would seem to make more sense that the throttling is done by PostgreSQL rather than requiring programmers to have to remember to include the extra function call before calling the fetch_func() themselves. Many thanks, Mark. --- Mark Cave-Ayland Webbased Ltd.
