Agree.
I suspect that this is a mal configured pgpool - the developer thinks that the
pool is reusing connections,
While it is, in fact, reopening them.

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.
