ClosedChanged Functionality and Performance Enhancements

PostgreSQL Database Installer Enhancement

Tenable Security Center 6.9.1 updates the PostgreSQL database installer to handle non-empty public schemas that contain non-Tenable Security Center tables. This improvement ensures that installation succeeds in environments with existing PostgreSQL schemas, reducing deployment complexity in shared database environments.

ClosedBug Fixes

• Fixed an upgrade failure where certain installations would abort during the migration to Tenable Security Center 6.9.0 due to broken trend charts.

• Fixed an issue where some scan targets containing dashes could be incorrectly treated as IP ranges rather than domain names during scanning.

• Fixed an issue where scan results were not completely deleted when they were removed from the application.

• Fixed an issue where certain queries failed when specific HTTPS certificate configurations were in place.
