Please build golang-github-lib-pq for EPEL7 (it was previously built for el6).
This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
I've no interest to build golang-github-lib-pq for epel7 and not sure either if this a current request, as the original request is from 2017. I'm closing the BZ, but if interested in maintain the package in EPEL, please, reopen it.
