Postgresql plugin error

error.JPG

Hello, I have above error while installing postgresql plugin in my Orthanc setup and want to know if I missed something. It seems like the error is not about configuration. Does anyone have any idea how to solve this?

Hello,

This indicates that you are using a version of PostgreSQL < 9.1:

But, PostgreSQL 9.1 was released 9 years ago (in 2011). We cannot provide support for such an old version of a third-party software.

Please upgrade the version of your PostgreSQL server.
