  1. Updating parallel.sgml's treatment of parallel joins

    Hi hackers,

Here is an attempt at updating parallel.sgml to cover Parallel Hash.
I will be neither surprised nor offended if Robert would like to put
it differently!

Thanks.

One thing that is slightly odd about that page[1] is that some places
use the style "<emphasis>parallel sequential scan</emphasis>" (lower
case, emphasis on first mention, head noun = "scan" or "join") and
other places use the style "<literal>Partial Aggregate</literal> node"
(title case, fixed width typeface, head noun = "node").

I think that page also needs a new <sect2> for "Parallel Append".
Perhaps the authors of commit ab727167 would like to write a patch for
that?  I'll be interested to see which style they go for...
