community package dependance issues

Hello,

on SUSE 15 platform:

package
https://download.postgresql.org/pub/repos/zypp/13/suse/sles-15.2-x86_64/pg_cron_13-1.3.0-1.sles15.x86_64.rpm

doesn't install because of a missing dependency
Problem: nothing provides openssl-libs needed by pg_cron_13-1.3.0-1.sles15.x86_64

package openssl-libs seems to exist only for rhel distributions.

Please, do you have any idea or repositories where you package (RPM) your products (here pg_cron) ?

thank you
