Thread: hashing improvements
Hi, 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.
