Hi!
Let me introduce ZTC 9.9.46 - set of zabbix templates for monitoring Linux servers and PostgreSQL, Slony, nginx and Apache running under Linux.
It's far from being perfect, but I hope it will be useful for someone, and I also hope to get some feedback and contributions.
Here is release announcement on my site:

And here is trac with more information:

As always, documentation (and trac configuration) sucks, but I'm going to improve it slowly.
Thanks.
