Re: select max(column) from parent table very slow

query on each child and a max on the set that is returned.
It is not.  Feel free to submit a patch for planagg.c ...
I think my patch to pgbench may have set your expectations of me a bit high ;)...

Actually I think this is the perfect opportunity for you -- a patch that
not only was absolutely unexpected, undiscussed, and posted without
previous warning, but one that you were actually asked about!  And
weren't you recently joking about giving Tom nightmares by sending
patches to the optimizer?

Yeah, but Tom is getting up there a bit, and that might mean a heart attack. Then what would we do? ;)
