Postgres as a service for supporting common application users

Dear All,

To further promote the use of PostgreSQL as a service, we need working
examples for common application users to understand what to do, and to
prepare data resources for them.
These users may use PowerBI, Excel, graphical packages and more specialist
applications such as ArcGIS.

Are there any information on how best to store image data, and enable
application users to simply add images into their applications.

Looking forward to hearing from you.

Regards,

Shao
