Hi, i am currently trying to migrate our foreman installation from MySQL to Postgres

packages installed are:

foreman-1.23.2-1.el7.noarch
foreman-cli-1.23.2-1.el7.noarch
foreman-debug-1.23.2-1.el7.noarch
foreman-ec2-1.23.2-1.el7.noarch
foreman-installer-1.23.2-1.el7.noarch
foreman-libvirt-1.23.2-1.el7.noarch
foreman-mysql2-1.23.2-1.el7.noarch
foreman-ovirt-1.23.2-1.el7.noarch
foreman-postgresql-1.23.2-1.el7.noarch
foreman-selinux-1.23.2-1.el7.noarch
foreman-vmware-1.23.2-1.el7.noarch
tfm-rubygem-foreman_hooks-0.3.15-1.fm1_23.el7.noarch
tfm-rubygem-foreman_memcache-0.1.1-2.fm1_23.el7.noarch
tfm-rubygem-foreman_setup-7.0.0-1.fm1_23.el7.noarch
tfm-rubygem-hammer_cli_foreman-0.18.2-1.el7.noarch

the error from the rake task "foreman-rake db:convert:prod2dev --trace" can be found in the attached file foreman_migration.log.

please advise on how to fix this.
