PostgreSQL version: 9.3.20
Operating system: Red Hat 7.0
Description:
JAN 28 you released in repository
https://download.postgresql.org/pub/repos/yum/9.3/redhat/rhel-7Server-x86_64/
the package gdal-libs-1.11.4-12.rhel7.x86_64 during the update in my RHEL7.3
it returns this error:
Error: Package: gdal-libs-1.11.4-12.rhel7.x86_64 (pgdg93)
Requires: libproj.so.12()(64bit)
but the PROJ package on the same repository is proj-4.8.0-4.el7.x86_64.rpm
with libproj.so.0.7.0 (the same thing with proj in the EPEL repository).
The package you have updated is therefore not updateable.
