I think we should try to make it automatic. I'm not sure how.
How about having a constant sized "fastupdate" buffer, of say 100 rows
or a fixed number of pages, and when that becomes full, the next
inserter will have to pay the price of updating the index and flushing
the buffer. To keep that overhead out of the main codepath, we could
make autovacuum to flush the buffers periodically.
