Day 66, perhaps the older servers have data that newer versions do not reproduce

It was last Sunday, July 23 that the site_aggregates update of 1500 rows issue was discovered.

Lemmy.ca made a clone of their database.

The UPDATE of 1500 rows in site_aggregates is an example of what keeps slipping through the cracks.

lemmy.ml as a long-running server may have data patterns in it that a fresh-install server does not easily match.

Lemmy.ca cloning a live database to run EXPLAIN was exactly the kind of thing I wanted to see from lemmy.ml 2 months ago.
