> First, although I work at Oxide, please don't think I speak for Oxide. None of this happened at Oxide. It informed some of the choices we made at Oxide and we've talked about that publicly. I try to remember to include the caveat that this information is very dated (and I made that edit immediately after my initial comment above).

I said oxide, because it's come up so frequently and at such length on the oxide podcast... Without that I probably wouldn't have commented here. It's one thing to comment on bad experiences, but at this point it feels like more like bashing. And I feel like an open source focused company should treat other folks working on open source with a bit more, idk, respect (not quite the right word, but I can't come up with a better one right now).

I probably shouldn't have commented on this here. But I read the message after just having spent a Sunday morning looking into a problem and I guess that made more thin skinned than usual.

> For most of that time (and several years earlier), the community members we reached out to were very dismissive, saying either these weren't problems, or they were known problems and we were wrong for not avoiding them, etc.

I agree that the wider community sometimes has/had the issue of excusing away postgres problems. While I try to avoid doing that, I certainly have fallen prey to that myself.

Leaving fandom like stuff aside, there's an aspect of having been told over and over we're doing xyz wrong and things would never work that way, and succeeding (to some degree) regardless. While ignoring some common wisdom has been advantageous, I think there's also plenty where we just have been high on our own supply.

Was that done in this thread?

I don't agree that we have been "bashing" Postgres. As far as I can tell, Postgres has come up a very small number of times over the years: certainly on the CockroachDB episode[0] (where our experience with Postgres is germane, as it was very much guiding our process for finding a database for Oxide) and then again this year when we talked about our use of statemaps on a Rust async issue[1] (where our experience with Postgres was again relevant because it in part motivated the work that we had used to develop the tooling that we again used on the Rust issue).

I (we?) think Postgres is incredibly important, and I think we have properly contextualized our use of it. Moreover, I think it is unfair to simply deny us our significant experience with Postgres because it was not unequivocally positive -- or to dismiss us recounting some really difficult times with the system as "bashing" it. Part of being a consequential system is that people will have experience with it; if one views recounting that experience as showing insufficient "respect" to its developers, it will have the effect of discouraging transparency rather than learning from it.

I'm certainly very biased (having worked on postgres for way too long), so it's entirely plausible that I've over-observed and over-analyzed the criticism, leading to my description.

I agree that criticism is important and worthwhile! It's helpful though if it's at least somewhat actionable. We can't travel back in time to fix the problems you had in the early 2010s... My experience of the criticism of the last years from the "oxide corner" was that it sometimes felt somewhat unrelated to the context and to today's postgres.

> if one views recounting that experience as showing insufficient "respect" to its developers

I should really have come up with a better word, but I'm still blanking on choosing a really apt word, even though I know it exists. I could try to blame ESL for it, but I can't come up with a good German word for it either... Maybe "goodwill". Basically believing that the other party is trying to do the right thing.

Well, I raised a general problem around 24/7/365 use cases (rooted in my operational experience, reinforced by the more-current words that I was replying to and the OP) and you called it "tedious", "low-info griping". Yes, that seems pretty dismissive.

(Is it fair? Though I thought the podcast episodes were fairly specific, they probably glossed over details. They weren't intended to be about those issues per se. I did write a pretty detailed post though: https://www.davepacheco.net/blog/2024/challenges-deploying-p... (Note the prominent caveat at the top about the experience being dated.))

> running an, at the time, outdated postgres, on an outdated OS

Yes, pointing to the fact that the software is old and the OS is unusual (it was never outdated; it was just not Linux) are common ways to quickly dismiss users' problems. If the problems had been fixed in newer versions, that'd be one thing. Many (if not all) of them hadn't been. But also: the reason we were running an old version was precisely that it was a 24/7/365 service and there was no way to update databases without downtime, especially replicated ones, nor a great way to mitigate risk (e.g., a mode for running the new software without updating the on-disk format so that you can go back if it's a disaster). This should be seen as a signal of the problem, not a reason to dismiss it (as I feel like you're doing here). As for the OS, I can only think of one major issue we hit that was OS-specific. (We did make a major misconfiguration related to the filesystem that certainly made many of our issues much worse.)

I get that it sucks to keep hearing about problems from years ago. All of this was on 9.2 - 9.6 -- certainly ancient today. When this comes up, I try to balance sharing my operational experience with the fact that it's dated by just explaining that it's dated. After all, all experience is dated. Readers can ignore it if they want, do some research, or folks in the PostgreSQL world can update me when specific things are no longer a problem. That's how I learned that the single-threaded WAL receiver had been updated, apparently in part because of our work: https://x.com/MengTangmu/status/1828665449850294518 (full thread: https://x.com/MengTangmu/status/1828665439234474350). I'll happily share these updates wherever I would otherwise share my gripes!
