Who wants to just run with a thousand entries? I have many small
instances running on AWS where that actually is an appreciable amount
of memory. Individually, any addition to pg_stat_statements shared
memory use looks small, but that doesn't mean we want every possible
thing. Futhermore, you're assuming that this is entirely a matter of
how much memory we use out of how much is available, and I don't
understand it that way.
