I get the following error while trying to connect to Postgres server 9.1.4. What am I missing? I am using pgAdmin 4 version 5.5

From their front page
pgAdmin may be used on Linux, Unix, macOS and Windows to manage PostgreSQL and EDB Advanced Server 9.5 and above.
9.1.4 is much older than that.

Thank you. Any recommendation on clients (GUI) to query 9.1.4?

set_config()is available in 9.1, but I'm guessing there is a context issue that is keepingpgAdminfrom using it. I would look at the Postgres log to see if you can get more information.
