You should be using a connection pooler for a load like that. PG backends are fairly heavyweight things --- you don't want to fire one up for just a single query, at least not when there are many such queries per second. I think pgbouncer and pgpool are the most widely used options, but this is a bit outside my expertise. regards, tom lane
