Better Connection Statistics

Hi everyone,

So, I haven't ever heard of this, but I could be missing something. Is there a module or extension for PostgreSQL keep connection statistics? I don't mean what's in pg_stat_activity, but cumulative. And not like what's in pg_stat_statements, but about the connections themselves. Nor even pg_stat_database, since that's only granular at the database level.

For instance, I want the number of transactions a specific connection has submitted. The number of queries. Total amount of CPU time consumed, etc. So far as I know, there is no module, statistic, or view that provides any of this. It occurred to me after one of our NOC guys asked us if a certain machine was spamming us with queries, and I realized I didn't know, and had no way of finding out. The best I can do is see if any are currently, this very second, executing something. If the connection happens to be between transactions when I poll pg_stat_statements, I get nothing.

I know pg_pool and pg_bouncer provide info like this, but we don't use those. Is there anything internal to PG that can... eventually get it?
