I'm using an EC2 on AWS running Amazon Linux 2. I'm trying to install Postgresql version 15 server along with the contrib libraries for various extension.
This is how I installed Posgres15
sudo rpm --import https://yum.postgresql.org/RPM-GPG-KEY-PGDG-15 sudo yum update -y sudo yum install -y postgresql15-server postgresql15-contribPostgreSQL server installs correctly but fails during the contrib package install due to a dependency on Python. I am able to install just the server alone:
sudo yum install -y postgresql15-serverHere is the error I get when installing postgresql15-contrib:

What am I missing? Why won't the postgresql15-contrib install find my python shared lib? Does it have to be python3.6 only? Is 3.7, 3.8 no good?
This is not actually answering your question, but you should know that the PostgreSQL yum repository does not officially support Amazon Linux (as can be seen on the list of available distributions). This sounds like exactly the kind of problem that could show up on an unsupported distributions.
I'd recommend you try a supported distribution -- if nothing else then just to initially prove that the problem is with Amazon Linux and not something else.
