Re: Can I get some PostgreSQL developer feedback on these five general issues I have with PostgreSQL and its ecosystem?

2. pg_dump misinterprets non-ANSI values for the "--exclude-*" options (at least the --exclude-table-data one, which is the one I've tested) on Windows, resulting in it being impossible to make more "sophisticated" backups of PostgreSQL databases; it's either all or nothing. Other programs, including my own test scripts and commands, are perfectly able to use any Unicode character sent from/through both cmd.exe and PHP CLI, but not pg_dump, so the idea that "Windows it at fault" here just doesn't seem true. (Although I don't doubt for a second that it often *is* the case... Microsoft is not a nice entity in any way.) I spent a lot of time and efforts experimenting with and asking about this, but eventually gave up and concluded that it was yet another bug in an open source project "only" on Windows with no real/pressing interest in fixing it. For me, this means that I lose a ton of fresh data every day, or have to make *gigantic* backups. (I have several huge "temporary debug log" tables whose data have zero long-term value but tons of short-term value.) It makes me feel crippled and excluded in an uncomfortable manner.

3. The ability to embed PG to run in an automatic, quiet manner as part of something else. I know about SQLite, but it's extremely limited to the point of being virtually useless IMO, which is why I cannot use that for anything nontrivial. I want my familiar PostgreSQL, only not require it to be manually and separately installed on the machine where it is to run as part of some "application". If I could just "embed" it, this would allow me to create a single EXE which I can simply put on a different machine to run my entire "system" which otherwise takes *tons* of tedious, error-prone manual labor to install, set up and maintain. Of course, this is probably much easier said than done, but I don't understand why PG's architecture necessarily dictates that PG must be a stand-alone, separate thing. Or rather, why some "glue" cannot enable it to be used just like SQLite from a *practical* perspective, even if it still is a "server-client model" underneath the hood. (Which doesn't matter at all to me, nor should it matter to anyone else.)

4. There is no built-in means to have PG manage (or even suggest) indexes on its own. Trying to figure out what indexes to create/delete/fine-tune, and determine all the extremely complex rules for this art (yes, I just called index management an *art*, because it is!), is just utterly hopeless to me. It never gets any easier. Not even after many years. It's the by far worst part of databases to me (combined with point five). Having to use third-party solutions ensures that it isn't done in practice, at least for me. I don't trust, nor do I want to deal with, external software and extensions in my databases. I still have nightmares from PostGIS, which I only keep around, angrily, out of absolute necessity. I fundamentally don't like third-party add-ons to things, but want the core product to properly support things. Besides, this (adding/managing indexes) is not even some niche/obscure use-case, but something which is crucial for basically any nontrivial database of any kind!

5. Ever since my early days with PG in the mid-2000s, I've tried numerous times to read the manual, wikis and comments for the configuration files, specifically the performance directives, and asked many, many times for help about that, yet never been able to figure out what they want me to enter for all the numerous options. At this point, it isn't me being lazy/stupid; it's objectively very difficult to understand all of that.

The practical end result of this is that I've always gone back to using the untouched default configuration file (except for the logging-related options), which, especially in the past on FreeBSD, *severely* crippled my PG database to not even come close to taking advantage of the full power of the hardware. Instead, it felt like I was using maybe 1% of the machine's power, even with a proper database design and indexes and all of that stuff, simply because the default config was so "conservative" and it couldn't be just set to "use whatever resources are available".

I wish so much for PG to have a mode where it self-tunes itself as needed, over time, based on the actual workload, or at least allowed some kind of abstract "performance mode" such as: "you are allowed to use significant system resources, PG", or: "You are one of my most important applications. Just use as much power as you currently need, but at least save about 10% for the rest of the system, will you?" Maybe this is also harder than it sounds to accomplish, but for somebody like me who has zero funding, I cannot hire some professional to sit down with me and fine-tune my system for $899/hour.
