Thread: BUG #15531: python-sqlobject shipped with EPEL 7 not compatible withPostgreSQL 9.6.11

The following bug has been logged on the website:

Bug reference:      15531
Logged by:          Martin vom Hagen
Email address:      martin@vhagen.de
PostgreSQL version: 9.6.11
Operating system:   CentOS 7.5
Description:

The python-sqlobject-1.2.2-3.el7.noarch shipped with EPEL 7 is not
compatible with PyGreSQL-5.0.6-1.rhel7.x86_64 from PostgreSQL 9.6.11

The python-sqlobject RPM requires "postgresql-python" meta RPM, which was
provided by PyGreSQL:4.0-9 (from CentOS 7 repo) and PyGreSQL:5.0.3-1 (from
PostgreSQL 9.6.10 Yum repo) as a migration path. In PostgreSQL 9.6.11
PyGreSQL:5.0.6-1 is shipped, which does provide the newer "python2-PyGreSQL
= 5.0.6-1", but not the "postgresql-python" meta RPM anymore. A dependency
resolution fails.

Steps to Reproduce:
1. install PostgreSQL 9.6 repo: yum install
https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm
2. yum install PyGreSQL
3. yum install python-sqlobject

Actual results:
Loaded plugins: etckeeper, fastestmirror, priorities
Loading mirror speeds from cached hostfile
17 packages excluded due to repository priority protections

               Not found
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Expected results:
A successful installation.

Additional info:
Newer upstream version of python2-sqlobject (note the "2") require
"python2-PyGreSQL" directly (e.g. on Fedora). But this RPM is not contained
in EPEL nor PostgreSQL Yum repo. Would it be a possible solution to include
it?
