Features I'd Like in PostgreSQL
Simply by larger sizes of compressed blocks, which are limited to page size in Postgres, and by improving the data locality by sorting, which is inherent for LSM-trees.
But if you want higher compression, you need to consider column-oriented DBMS, such as ClickHouse[1]. They are unbeatable in terms of data compression.

Setting the TZ environment variable avoids thousands of system calls
Syscalls can be heavier than expected. One example is when an application is run inside gVisor. Another example is when a lot of eBPF code is attached. A third example is when a program is run under strace.
Disclaimer: I'm working on ClickHouse[1], and it is used by thousands of companies in unimaginable environments. It has to work in every possible condition... That's why we set the TZ variable at startup and also embed the timezones into the binary. And we don't use the glibc functions for timezone operations because they are astonishingly slow.

Efficient and performance-portable vector software
It is a nice paper, but for practical applications on fixed-size numbers up to 64 bits, as well as for tuples on fixed-size numbers, and for partial sorting, it does not beat Radix Sort (on moderate-sized arrays).
I have tested it in ClickHouse, but end up with this:
https://github.com/ClickHouse/ClickHouse/blob/master/src/Com...
PS. It's strange that Google's paper dismisses djbsort: https://sorting.cr.yp.to/ - also in the class of sorting networks, but introduced a few years ago.

Show HN: HyperLogLog in Zig
[1] https://github.com/ClickHouse/ClickHouse/
What is often forgotten in designing a data structure for a cardinality estimator - is that it should work well not only for a few large states but also for a large number of small sets.
For example, in a query like follows:
SELECT URL, COUNT(DISTINCT UserID) FROM pageviews GROUP BY URL -
Show HN: ClickHouse-local – a small tool for serverless data analytics
ClickHouse will throw an exception in case of not enough memory and continue to serve other queries. Under certain configurations it can OOM as well.
> How confident are you that your chosen dataset is neutral?
I have no idea if it is "neutral", I picked it randomly.
I test ClickHouse on every interesting dataset, see here: https://github.com/ClickHouse/ClickHouse/issues?q=is%3Aissue...
The reason - I love working with data :) If I see a dataset, I load it into ClickHouse - this is the first thing I do. This is not a kind of marketing or promotion of ClickHouse - you know, if it were some directed task, it would be uninteresting for me.
> curl https://clickhouse.com/ | sh
It feels a bit weird to not use a subdomain (install.clickhouse.com) or a specific route for this, and instead mix this in with your marketing site.
