BuildRequires: s/postgresql-devel/postgresql-server-devel/
    
    Development files used to build PostgreSQL extensions is moved to
    'postgresql-server-devel' package, client library is moved to 'libpq'
    (and 'libpq-devel').  Per devel list discussion:
    https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/U3XR5EGU2TPI2CDHBRBUD4M4LK5OHKU3/
    
    The 'libpq-devel' BR should be ideally dropped in future.
