current_schemas()

I would like to know how to use current_schemas(), since SELECT current_schemas(); didn't work in
PostgreSQL 7.4 and 8.0 psql.

The current effective value of the search path can be examined via the SQL function
current_schemas(). This is not quite the same as examining the value of search_path, since
current_schemas() shows how the requests appearing in search_path were resolved.

teste=# \dn
********* QUERY **********
SELECT n.nspname AS "Name",
u.usename AS "Owner"
FROM pg_catalog.pg_namespace n LEFT JOIN pg_catalog.pg_user u
ON n.nspowner=u.usesysid
WHERE (n.nspname NOT LIKE 'pg\\_temp\\_%' OR
n.nspname = (pg_catalog.current_schemas(true))[1])
ORDER BY 1;
**************************
