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.

didn'tknow, 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.
