I wonder what you think about including this little performance item:

https://www.postgresql.org/message-id/E1eotSQ-0005V0-LV@gemulon.postgresql.org

especially considering the part of the commit message which states

...Still, testing shows
that this makes single-row inserts significantly faster on a table
with many partitions without harming the bulk-insert case.

I recall seeing those inserts being as much as 2x faster as partition
count grows beyond hundreds. One might argue that we should think
about publicizing this only after we've dealt with the
lock-all-partitions issue that's also mentioned in the commit message
which is still a significant portion of the time spent and I'm totally
fine with that.

Thanks,
Amit
