This problem exists in CVS tip *without* the unknownin/out patch:

# psql -U postgres testjp
Welcome to psql, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit

testjp=# SELECT SUBSTRING('1234567890' FROM 3);
substring
-----------
3456
(1 row)

testjp=# select * from pg_type where typname = 'unknown';
typname | typnamespace | typowner | typlen | typprtlen | typbyval |
typtype | typisdefined | typdelim | typrelid | typelem | typinput |
typoutput | typreceive | typsend | typalign | typstorage | typnotnull |
typbasetype | typtypmod | typndims | typdefaultbin | typdefault
---------+--------------+----------+--------+-----------+----------+---------+--------------+----------+----------+---------+----------+-----------+------------+---------+----------+------------+------------+-------------+-----------+----------+---------------+------------
unknown | 11 | 1 | -1 | -1 | f | b
| t | , | 0 | 0 | textin |
textout | textin | textout | i | p | f |
0 | -1 | 0 | |
(1 row)

This is built from source with:
