This happens via command line as well, this is an issue with Zabbix, and not with Ansible. I suggest closing this bug report out.

The way with_items works, is it will loop through the job for each item.
So when zabbix-server is installed first, it installs zabbix-server-mysql. If you tried to install zabbix-server-pgsql after that you would get the conflict we are seeing.
Therefore the bug is not with with_items
However, I do believe a bug is present because the also failed.
- name: Install Zabbix Repo
yum: name=http://repo.zabbix.com/zabbix/2.4/rhel/6/x86_64/zabbix-release-2.4-1.el6.noarch.rpm state=present
- name: Install Zabbix
yum: name=zabbix-server,zabbix-server-pgsql state=present
This should have been comparable to yum install zabbix-server zabbix-server-pgsql in my opinion, and it clearly is not actually doing that, it is still installing one at a time which causes the error.
If you reverse the order it works, which proves its installing it one at a time.

- name: Install Zabbix Repo
yum: name=http://repo.zabbix.com/zabbix/2.4/rhel/6/x86_64/zabbix-release-2.4-1.el6.noarch.rpm state=present
- name: Install Zabbix
yum: name=zabbix-server-pgsql,zabbix-server state=present
So the bug that needs to be addressed, is how yum module installs things one at a time, instead of as one transaction if listed on the same line and separated by commas.
On a side note, installing zabbix-server-pgsql installs zabbix-server as a dependency so you do not actually need to list both.seperated

The yum module works differently in combination with with_items than most other modules due to some magic behind the scenes.
when using yum, Ansible will concatenation the list of packages to install into a single yum invocation and not multiple runs like other modules.

ah cool, then the issue is the same, its installing one a time whether with_items is used or not it would appear

It seems I'm having the same problem. Maybe I'm missing something, but I'm not seeing in yum.py -> install(...) where it's concatenating the items together. It seems to be doing a cmd = yum_basecmd + ['install', pkg] for each item in items.

@koebbe It is installing them one at a time basically. And the zabbix module installs zabbix-mysql if installed by itself, it then tries to install zabbix-psql which conflicts with zabbix-mysql and fails. I think this is expected behavior, and as such I am not sure what should be done.
@bcoca @abadger Any ideas on how you want the community to solve this specific issue?

to clear up, the with_items optimization with some modules makes it take the list at 1 time, instead of executing the module each time per item in list (with file transfer and execution), not that the module itself runs all items at once in the command line (which it can or cannot depending on module author).
I would look into why the author iterates over each package (probably to do correct reporting) before changing the way the module operates.

I would rather have yum run a lot faster with a long list of packages (install them in one command), than to have detailed reporting which package was installed, removed,... But it should be possible to have both.
