Which of the following databases is NOT supported by IIQ?

SailPoint IdentityIQ supports a variety of databases for its deployment, and PostgreSQL is not one of the officially supported options. The platform is designed to work efficiently with commercial databases that offer features required for identity governance and compliance.

IBM DB2, MySQL, and Microsoft SQL Server are all listed in SailPoint's documentation as compatible databases. These databases are commonly used in enterprise environments and offer capabilities such as scalability, reliability, and robust support for transactions, which are essential for an identity management system.

PostgreSQL, while a powerful and popular open-source database, does not currently align with the supported environments in the context of IdentityIQ. This may be due to specific integrations, performance benchmarks, or support considerations that SailPoint has determined in their product development cycle.
