I'm having a hard time imagining how you'd actually implement that. For example, this: https://wiki.postgresql.org/wiki/Aggregate_Histogram requires that a "limit" be specified ahead of time. Is there a principled way to increase or decrease this kind of limit over time, and have the new buckets contents "spill into each other"? -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
