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.
