No.
You can use postgresql for caching, but caches don't require the data
durability that a database offers, and can be implemented much more
efficiently.
You can use postgresql to provide message queue services and it
does so reasonably well, particularly when the messages are generated within
the database. But it's not going to do so as efficiently, or be as easy to
monitor, to make highly redundant or to scale across a whole datacenter
as a dedicated message queue service.
You could use postgresql to store binary blobs, but it'd be a horrifically
inefficient way to do it. (Using postgresql to store the metadata, while
the content is stored elsewhere, sure).
Use the right tool for the job.
