To be precise, this truncates timestamps on write, and also on querying. Last time we tried this upgrade, it was to 1.7.1: #7006. I have a bit of a preference to try upgrading to 1.7.1 again, to minimize variables. That way if something goes wrong we are less likely to second guess ourselves, like "was there something new in 1.8 or 1.9 that did it?" Then hopefully the subsequent upgrade to 1.9.2 will be a nothingburger. |

Version v1.5.0 was released in January 2020, over five years ago. We have attempted to update this package several times since then -- first to v1.6.0, later to v1.7.1 -- but have reverted the change due to nigh-inexplicable performance regressions each time. Since our last attempt, we believe we have addressed the underlying issue by truncating timestamps when we talk to the database (see #7556) so that our indices don't try to track nanosecond precision.
We are now ready to reattempt updating this package to v1.7.1 again. If that goes well, we will further update it to the newest version.
Fixes #5437
