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.
Anyhow, I was suggesting the faclity be off by default - I see no point
in enabling where people don't need it, even if the resource RAM,
processor, whatever, were minimal.
