current_schemas()

Hello,

In http://developer.postgresql.org/docs/postgres/runtime-config.html,
the SEARCH_PATH variable description mentions the use of
current_schemas(), but this function doesn't exist (or it didn't exist
last time I updated:
#define CATALOG_VERSION_NO 200209021
)

What exists is current_schema(), but it doesn't expand to the full
search path; apparently, only the first item that exists:

testing=# set search_path to '$user', 'public', 'alvh1', 'alvh2';
SET
testing=# select current_schema();
current_schema
----------------
public
(1 row)

This is not good:

testing=# \d foo
Table "alvh1.foo"
Column | Type | Modifiers
--------+---------+-----------
a | integer | not null
Indexes: foo_pkey primary key btree (a)

(and alvh1 does not appear on current_schema)

Is this a bug?
