wcs oam db installation error (amazon linux 2)

[sangsoo]

Hello.
I want to use oam sdk to manage WCS metrics.
I am trying to install and configure postgresql and timescaledb on a new instance of amazon linux 2 (AWS EC2).
There were some difficulties in the process. I would like to receive your feedback.

Postgresql installed version 11 (11.5) using amazon-linux-extras. (success)
-Versions 9.6 and 10 were difficult to install, so I chose version 11. (postgresql-libs)
2. timescaledb added the repo by referring to the documentation.
-https://docs.flashphoner.com/display/WCSOAM10EN/Stream metrics storage in Timescale DB
-https://docs.timescale.com/latest/getting-started/installation/rhel-centos/installation-yum
3. However, an error occurred during the installation (timescaledb-postgresql-1.6).
- error "Requires: postgresql11-server> = 11.4"

[Questions]
1. Do I need to configure Cent OS 7 for wcsoam?
2. Is there a way to configure db on amazon linux 2?

Thanks.

Good day.
According to TimescaleDB documentation, it supports the following instances:

So you probably have to install Timescale using one of them. We have tested Postgresql 9.6 + TimescaleDB on Centos7, also we use timescaledb:latest-pg9.6 Docker image.
