Thanks, I missed that one. Unfortunately it produces a false negative if a
user hasn't had their search path explicitly set, e.g.:

postgres=# CREATE ROLE sp_test LOGIN;
CREATE ROLE
postgres=# \drds sp_test
No matching settings found.
postgres=# \c - sp_test
You are now connected to database "postgres" as user "sp_test".
postgres=> SHOW search_path ;
search_path
----------------
"$user",public
(1 row)

postgres=> \c - postgres
You are now connected to database "postgres" as user "postgres".
postgres=# ALTER ROLE sp_test SET search_path ="$user",public, foo;
ALTER ROLE
postgres=# \drds sp_test
List of settings
Role | Database | Settings
---------+----------+-----------------------------
sp_test | | search_path="$user", public, foo

Also it's psql-specific, so doesn't really lend itself as a global solution.

The custom view will have to do for now.
