The above seems to be part of the problem. Looks like you have two
repositories for pgdg93.

Are you sure the AMI did not already have a repo for Postgres?

The above would seem to be the second problem and related to the first.
When I peeked into:

http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-ami201503-93-9.3-2.noarch.rpm

it showed that it was looking for:

https://download.postgresql.org/pub/repos/yum/9.3/redhat/rhel-6-$basearch


Seems you are trying to install a RH 7 package on an OS that is looking
for a RH 6 package. In other words yum is finding the RH 7 repo before
the RH 6 repo.
