Hello, If I'm not mistaken the latest available rpms for Red Hat 7.3 is missing the signature, doing a simple
$ > rpm -qpi https://download.postgresql.org/pub/repos/yum/9.3/redhat/rhel-7.3-x86_64/postgresql93-server-9.3.20-3PGDG.rhel7.x86_64.rpm " Gives me, $ > Name : postgresql93-server $ > Version : 9.3.20 $ > Release : 3PGDG.rhel7 $ > Architecture: x86_64 $ > Install Date: (not installed) $ > Group : Applications/Databases $ > Size : 16551335 $ > License : PostgreSQL $ > Signature : (none) $ > Source RPM : postgresql93-9.3.20-3PGDG.rhel7.src.rpm $ > Build Date : tor 7 dec 2017 22:41:49 $ > Build Host : koji-rhel7-x86-64-pgbuild $ > Relocations : (not relocatable) $ > URL : http://www.postgresql.org/ $ > Summary : The programs needed to create and run a PostgreSQL server $ > Description : $ > PostgreSQL is an advanced Object-Relational database management system (DBMS). $ > The postgresql93-server package contains the programs needed to create $ > and run a PostgreSQL server, which will in turn allow you to create $ > and maintain PostgreSQL databases. Notice the Signature "(none)". Doing the same command on previous rpm's reveals a the signature "DSA/SHA1, ons 8 nov 2017 21:52:18, Key ID 1f16d2e1442df0f8" Am I missing something ?
