Обсуждение: Viewing another role's search path?

Is there some simple way of viewing the search path (or other
role-specific setting) for a role different to the current role? Apart from
querying 'pg_db_role_setting' directly?

Just wondering if I'm missing something obvious.

Regards

Thanks, but what I'm looking for is a more elegant (built-in?) way of extracting
the contents of the configuration array which is useable for people who don't
want to poke around in the system catalogues. I've created a view
which does this,
but I want to confirm if there's anything along the lines of "SHOW
search_path FOR ROLE foo"
which I've missed and would save the trouble of maintaining the view.

\drds [ role-pattern [ database-pattern ] ]
Lists defined configuration settings. These settings can be
role-specific, database-specific, or both. role-pattern and
database-pattern are used to select specific roles and databases to
list, respectively. If omitted, or if * is specified, all settings are
listed, including those not role-specific or database-specific,
respectively.

The ALTER ROLE and ALTER DATABASE commands are used to define per-role
and per-database configuration settings.

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.
