Re: pg_config header files are missing - Postgres 13 - Amazon Linux 2

This problem posted in OP is resolved. I did some workaround. I copied the
required "pg_config*.h" from another machine where PG13 was installed via
amazon linux 2 repos.

I'm not sure whether it worked "by chance" or otherwise, because it looks
like Amazon Linux 2 is based on "RHEL 7" as per below:

Note the "ID_LIKE":
----
# cat /etc/*elease
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
Amazon Linux release 2 (Karoo)
----

And:
---
# rpm -E %{rhel}
7
----

Thanks!
