I'm following the instructions from here. I try and run
yum localinstall http://yum.postgresql.org/9.4/redhat/rhel-5-i386/pgdg-centos94-9.4-1.noarch.rpm
which returns the fault cannot open file... Skipping.
I tried to wget
the file and ran yum install pgdg-centos94-9.4-1.noarch.rpm
which returns the error
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 442df0f8
Public key for pgdg-centos94-9.4-1.noarch.rpm is not installed
Sorry, server admin isn't my strong suit and am struggling to figure out what to do.
