I am not a Windows guy but I (with help) managed to get IOCP working for this in a basic prototype. Will share publicly soon. I also sketched out an IoRing version (if you are interested in helping debug and flesh that out let me know!).

BTW I have patches for PostgreSQL AIO on FreeBSD, which I will propose for v19. It works pretty well! I was trying to keep out of Andres's way for the core architectural stuff and basic features ie didn't want to overload the pi

Surprisingly, they are still taking orders: https://store.planetcom.co.uk/products/astro-slide I suppose this means that they still have a firm intention to produce eventually, hopefully even with an updated chipset gi

I had various Psion models in the 90s. Several of the people involved in the design of those things went to do modern-ish devices with Psion series 5-style keyboards, including the Cosmo Communicator. I was curious enough to back the Astr

After it was dropped from PostgreSQL, a team from IBM showed up on the mailing list (see one of my other answers for link), so perhaps that is now going to happen! I think it's a case that they were using it, but didn't realise t

Well said. I've been able to debug PostgreSQL issues reported by [closed] Solaris users by booting illumos inside a virtual machine on my laptop in minutes... I want to keep AIX support, for, well mainly irrational nostalgic reasons

We (the denizens of pgsql-hackers@postgresql.org) didn't see any AIX users or developers or other interested parties in our community... There was a group in France, but they disbanded... However, after AIX was dropped in the Postgre

POSTGRES was developed on SunOS (and its close cousin 4.3BSD or 4.2?). It's not so hard to support Solaris, as it was so influential that Linux uses a lot of similar things, including for example the ELF format and linker details, the

This is fantastic work, thanks. Hmm, what else... let's see... Xenix also really, really wants to be free! What a magnificent piece of forgotten computer history it is. https://en.wikipedia.org/wiki/Xenix

Reflinks and copy_file_range() are just landing in OpenZFS now I think? (Block cloning)

... but the BSDs did have support for SystemV binaries, through modules compat_svr4 and compat_ibcs2, so the grand parent comment made perfect sense to me. Not sure why there were two and I don't plan to go down that rabbit hole tod

Fun read. I'm pretty sure there were ways to run SCO SysV binaries unmodified on Linux (and I think FreeBSD and others), back in the day. Maybe something to do with ibcs2?

One technical problem is the WAL records changes to "shared" relations (stuff like the catalogues of databases and users that are global to the whole "cluster", not just one database), and those are mixed up with changes

Thanks! Author/developer here, happy to answer any questions about this topic.

The nostalgia is overwhelming. Learned BASIC, Z80 and 6502 assembler from these little cartoon robots.

Me too. But I think it led to more learning and less gaming! I did finally get a Speccy... recently!

FWIW I just removed pg_attribute_always_inline from those three comparator functions in tuplesort.c and it made no difference to the generated code under GCC 10 at -O2. If we can show that's true for Clang and MSVC too, maybe we shoul

Speaking as the author of that change, and also as a long time user of C++ (in other projects), I hear ya! But I don't have the power to make PostgreSQL switch to C++. Years ago, std::sort() vs qsort() was almost a standard example o

It's interesting that uniq is spelled unique in that video. I wonder who changed that!

I haven't followed it or tried it, but supposedly you can boot up a pure open source Darwin system. Certainly it has been very useful for me as a cross-platform developer to be able to browse its source and understand quirks of system

Some time in the early-ish 90s when I was a student I worked at a tiny place doing software development, targeting various commercial Unixes. Development was done on a lowly 486 running some variant of SCO System V UNIX, and I vaguely reca

I incorrectly assumed Norse and old English genders and cases ought to line up neatly and wouldn't have caused the whole system to be thrown out the window on contact. I stand corrected. Thanks! https://en.wikipedia.org&#x

From a nearby reply there is a clue that it's a new Americanism. I have to resist the urge to send a complaint... I'm not ready to become an old geezer who complains about things changing. But I admit that I grit my teeth when p

Edited: I guessed wrong, see Tagbert's answer. It was Norse contact (erm, the ones in the north, not the Normans who were French-speaking ethnic Norse people in the south). I thought it probably had more to do with the influence of No
