Hi Cary,
thanks for reaching out.
The obvious blocker is availability of hardware. We don't have build
hosts. The other question would be if those build hosts could keep up
with the speed of the other architectures. Currently all supported
architectures are about the same speed, so we can build all packages
synchronously, which has helped a lot with keeping repository quality
up. Looking at Debian's riscv64 build hosts, they are often much
slower than the others.

Thanks, this is very helpful.
I noticed that for the recently added loong64 support in PGDG APT, the
loongfans.cn community provided a 3B6000 board as the PGDG build host.
Perhaps we could use that as a practical reference point when Highgo
team looks for suitable RISC-V hardware that can keep up with the
build demand synchronously.
I'll reach out to Highgo's contacts in the RISC-V community in China
and explore whether we can procure a RISC-V machine with comparable
or better specifications and have it sent to you.
Alvaro Hernandez also reached out and expressed interest in RISC-V
support, so it looks like there is some interest from others in the
PostgreSQL ecosystem as well.
I'll see what options we can find and keep you posted. In the mean
time, if you can share with me privately a mailing address to send
the hardware to, it would be greatly appreciated!
Best regards
Cary Huang

Do you have any idea what the main bottleneck is with the Debian
riscv64 build hosts? Is it primarily CPU performance, or are
there other factors such as memory or I/O?
If you happen to know the hardware specifications of those build
hosts, or have a link to them, or if you have the desired RISC-V
hardware specs, that would also be very helpful. It would give us
a better reference when looking for suitable RISC-V hardware.
thanks a lot!

TBH I don't know, I'm just seeing Debian's riscv64 build and CI hosts
lagging behind often. I never checked the details.

https://db.debian.org/machines.cgi has the specs for some of the
.debian.org hosts.
