QUESTION
Exact type information can be found in Postgres
I noticed that the type information is a bit inaccurate regarding miltidimensional arrays:
...ANSWER
Answered 2022-Mar-14 at 10:17This is the standard bevahior according to the manual :
The current implementation does not enforce the declared number of dimensions either. Arrays of a particular element type are all considered to be of the same type, regardless of size or number of dimensions. So, declaring the array size or number of dimensions in CREATE TABLE is simply documentation; it does not affect run-time behavior.

My goal is to connect two QEMU-KVM VMs on an overlay network. Each VM is running on a separate physical host and must have a static IP on the network 10.0.0.0/24. To achieve this goal, I want to use an OVS bridge with DPDK. I want to use the vhost-user-client protocol to connect the OVS bridge with the VMs.
My physical setup is the following: two physical machines equipped with a Mellanox ConnectX6-DX, and connected back-to-back (no physical switch). What I want to achieve is this:
...ANSWER
Answered 2022-Feb-12 at 16:38 suspect that the problem is related to the LINK_DOWN status of the vhost-client-1 port
[Answer] Yes, the cause for packet not reaching VM is OVS sees the interface down. Even with the presence of a rule to forward traffic from dpdk0 to vhost-client-1 the packets will be dropped.
The primary cause of link not up
can be due to the qemu configuration memory backed
with hugepages not being used. Vhost-USER port created by DPDK=OVS resides on the huge page memory area and access to the same is required.
A similar DPDK-QEMU StackOverflow address the use of viritio-client (via cmdline). So please adapt the settings shared into the link to virsh xml

QUESTION
I'm having some trouble installing the python cryptography
package on my raspberry pi, specifically with python version 3.9.8 (installed with pyenv). The cryptography
package is installed on my system using pacman (python-cryptography
package), and thus works using the main python interpreter (3.10.1). However, I need some version of python 3.9 specifically for another package I am using in this project. Any time I try to install cryptography
through the python 3.9.8 environment, I get the following error:
ANSWER
Answered 2022-Jan-14 at 19:59@jakub's solution ended up solving the problem for me. I uninstalled the version of rust that was installed through pacman
. To replace it, I installed rustup
and then using rustup
, installed the latest nightly version of rust (1.60). Once I did that, installing the cryptography
package worked just fine.
If you are using rustup
, just make sure that you add ~/.cargo/bin
to your PATH
before installation. Also, the command I used to install rust through rustup was rustup toolchain install nightly
.

Answered 2022-Jan-28 at 19:51You can try fiber library for this issue. In fiber you can create your end points with app variable app := fiber.New()
. If you pass this app variable to other functions with pointer and create an end point inside of the that function as you would like. Finally start to serve this app on main function.
