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!
