Error executing action `install` on resource 'package[pgdg-centos93]' - postgresql

Question

Environment
Chef
CentOS
PostGres
Rails
Amazon cloud server
$ cat /etc/redhat-release
CentOS release 6.7 (Final)
$ uname -a
Linux ip-10-0-0-250 2.6.32-504.8.1.el6.x86_64 #1 SMP Wed Jan 28 21:11:36 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Put an Amazon CentOS instance to sleep for a couple of months and started it again today. To bring everything up-to-date, the "magic" should happen (figure of speech) with sudo chef-client, at least that was what was expected. And to my current experience for this particular , Chef has brought to my project almost more overhead than gain in time. (NOTE: This is a side comment related to a personal experience.)
Here is my latest headache

Any pointers are most desperately welcomed. I just don't manage to understand the ERROR
UPDATE
As suggested
$ sudo rpm -U /var/chef/cache/pgdg-centos93-9.3-1.noarch.rpm

UPDATE 2
Removed package pgdg-centos93-9.3-2.noarch which was newer than the one Chef was trying to install
yum remove pgdg-centos93-9.3-2.noarch
then ran sudo chef-client -l debug again.
Ran into another blocking issue that once resolved takes me to the first problem I had. So I am going in circles. Will validate the one helpful answer because, I believe that there is no easy solution to my problem.

Answer 1

The error is that the command rpm -U /var/chef/cache/pgdg-centos93-9.3-1.noarch.rpm has an exit code of 2, which indicates there was an error. Either run that command by hand to see the error details or run chef-client -l debug to enable Chef's debug-level output which will include the stdout and stderr from the subprocess.
So your broader question: Chef is not magic nor is it a Platform-as-a-Service on its own. Chef itself offers fairly basic primitives like package installs and templated config files, and in general those just do what they say on the tin. When you start either building your own complex cookbooks or using the community cookbooks you can get much more turn-key magic like "add this to your run list and out pops a PostgreSQL server" but with that complexity comes a lot more bugs. Community cookbooks especially are of widely varying quality and you should always check if something is from an author you personally or institutionally trust and if not probably read all the code in it and make sure you like it. Same basic process as with any software development environment when you start consuming external tools/libraries/gems/packages/etc.
