| Review the PostgreSQL software library directory and any subdirectories. |
If any non-PostgreSQL software directories exist on the disk directory, examine or investigate their use. If any of the directories are used by other applications, including third-party applications that use the PostgreSQL, this is a finding.
Only applications that are required for the functioning and administration, not use, of the PostgreSQL software library should be located in the same disk directory as the PostgreSQL software libraries.
If other applications are located in the same directory as PostgreSQL, this is a finding.
