Good to know. Last time I recall a DB upgrade being mentioned, it was when pg15 became the new minimum so I assumed this was the same case. That one was required since they used some new feature in pg15 (don't recall the specifics, but my test instance that was on pg14 failed the DB migrations for that lemmy release, and that was why)
Ah, interesting. That experience combined with the wording of "this update requires postgres 16", I can see where the confusion comes from.
Interestingly enough, they fixed the documentation. Now it says "We recommend upgrading to PostgreSQL 16 due to a known memory leak in PSQL 15. To use the new image proxy feature, pict-rs version 0.5+ is required." https://join-lemmy.org/news/2024-06-07_-_Lemmy_Release_v0.19.4_-_Image_Proxying_and_Federation_improvements
