VMware Postgres must provide nonprivileged users with minimal error information.
An XCCDF Rule
Description
<VulnDiscussion>Any database management system (DBMS) or associated application providing too much information in error messages on the screen or printout risks compromising the data and security of the system. The structure and content of error messages must contain the minimal amount of information. Databases can inadvertently provide a wealth of information to an attacker through improperly handled error messages. In addition to sensitive business or personal information, database errors can provide host names, IP addresses, user names, and other system information not required for troubleshooting but very useful to someone targeting the system.
