I've attached a simple patch which should improve the performance of
hashname() and reduce the penalty incured when NAMEDATALEN is increased.
I posted this to -hackers a couple days ago, and there haven't been any
major complaints. It passes the regression tests. See -hackers for more
discussion, as well as the suggestion from Tom Lane on which this patch
is based.
Unless anyone sees any problems, please apply for 7.3.
Cheers,
Neil Conway
