Hello List, I can't seem to find a pkgconfig file for postgresql on centos 6 or centos 7. Centos packages installed $ rpm -qa|grep postgresql postgresql-server-9.2.24-1.el7_5.x86_64 postgresql-9.2.24-1.el7_5.x86_64 postgresql-devel-9.2.24-1.el7_5.x86_64 postgresql-libs-9.2.24-1.el7_5.x86_64 Centos 6 packages installed postgresql-server-8.4.20-8.el6_9.x86_64 postgresql-devel-8.4.20-8.el6_9.x86_64 postgresql-8.4.20-8.el6_9.x86_64 postgresql-libs-8.4.20-8.el6_9.x86_64 postgresql-contrib-8.4.20-8.el6_9.x86_64 Any ideas? Thanks, Steve
