I have set up a new postgres installation and have to meet the security requirements from my company.
There is one requirement were i'm not quite sure:
Database functions which allow access to other network services (e.g. ,SMTP, HTTP, SNMP, FTP etc.), must be deleted or deactivated.
Motivation: Some database systems provide functions that are normally offered by an application server. For instance it is possible via special stored procedures to send e-mails or launch web queries to external systems.
I have installed postgres (PostgreSQL) 9.3.4. Are there any functions like this in a standard installation on Red Hat Enterprise Linux Server release 6.5 (Santiago)?
