> I was told that "The amazon linux is compatible with Centos 6.x". Does that correspond to RHEL 6? Is there a
commandI could use to find out?
Not quite.
Amazon Linux is RHEl/CentOS/Fedora derived, but it's not based on exactly RHEl/CentOS 6 or
exactly RHEl/CentOS 7.
This is its current libpoppler:
$ rpm -qf /usr/lib64/libpoppler.so.37
poppler-0.22.5-6.15.amzn1.x86_64
I don't know if this is an option to you, but CentOS 6 is available as an AMI on AWS,
so you could directly run that? Also AWS offers RDBMS as a service and they do have
PostgreSQL + PostGIS in their offerings (see "RDS").
