      OH: "PostgreSQL is the Linux of databases" It's probably equally unstoppable and will completely dominate the database ecosystem in the next 10-20 years. What's your opinion on this?

      I think that "one size fits all" is a myth. #PostgreSQL has many technical advantages, but two problems damage it a lot: 1) its community doesn't make criticism, which is essential to improve 2) there is no proper bug tracker

      tbh no one likes taking criticism.. try proposing as recommendations instead of criticisms

      Make actually meant make. I'm not complaining about some bad reply I received, it didn't happen. I'm observing that the PostgreSQL community only says great things about their favorite DB. As a consequence, most of them don't feel that its flaws should be fixed.

      I can definitely agree with that. Try discussing the benefits of a sophisticated execution plan cache (e.g. Oracle's) with them 😁

      I'd be curious as to who you talk to :-) most of the people I talk to in the postgres community would definitely want access to those benefits (whether by an identical solution or not is a different question, but something to solve the same very much existing problem)

      We've long claimed: - our planner is so good we don't need hints and that when it's not you should tell us and we fix it (we don't) - our replication story is good - that nobody wants/should want automated failover - our IO stack is a good idea - not using threading is awesome …

          I'd add autovacuum. But I understand that getting rid of it requires a major architectural change and I don't know if it's realistically possible.

          There's plenty more. Not sure about autovacuum in particular however: While our scheduling around it needs improvement, there's also some substantial gains from not needing full undo. FWIW, it's definitely fixable. There are actually quite a few patches around undo/zheap out.

          Often that's because we'd determined, quite possibly justified at the time, that we can't do a good job at X fully/… due to being a small open source project. Sometimes we were too defensive to admit that. Over time may of those shortcuts became enshrined as good ideas.

          Pretty much the thing that annoys me the most right now is that logical replication is literally broken if you consider failover. Five years and failover still destroys logical replicas.

          And even if we do fix it it'll take at least a year to get in, during which time you're pretty much screwed, or you can tick off some debug things that will screw up all your other queries...
