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.
