TYPE of TEMP table does not seem to get set

Hello, I am hoping that I'm just missing some kind of syntax tweak, but after experimenting a bit, I cannot seem to get this working.

I have a view "configurations.tp_transactions" which is a blend of many tables using INNER and LEFT JOINs. I want to populate a temp table from which I can obtain the data and programmatically write queries to operate on that data using certain PLPGSQL functions in a uniform fashion. I have several functions which all expect a single argument of the type "configurations.tp_transactions".

I am running 9.0.5 on CentOS 5 64 bit

Here is the schema of "configurations.tp_transactions"

network=> \d configurations.tp_transactions
View "configurations.tp_transactions"
Column | Type | Modifiers
---------------+----------------------+-----------
id | integer |
spid | integer |
sponsor_mtype | character varying(5) |
sponsor_spid | integer |
membertype | character varying |
trans_type | smallint |
trans_id | integer |
trans_date | date |
discount_amt | numeric(6,2) |
cv_mult | real |
reb_mult | real |
comm_mult | real |
rebate | numeric |
reb_com | numeric(5,4) |
pp | numeric(6,5) |
cap | integer |
receivable | numeric(8,2) |
ma_id | integer |
ma_spid | integer |
ma_mtype | character varying(5) |
amount | numeric |
pp_value | numeric |

network=> SELECT * INTO TEMP TABLE myt
FROM configurations.tp_transactions
WHERE membertype <> 'x'
AND configurations.tp_transactions.trans_id IN (920787);
SELECT 1

network=> \d myt
Table "pg_temp_47.myt"

network=> \df configurations.myself
List of functions
Schema | Name | Result data type | Argument data types | Type
----------------+--------+------------------+--------------------------------+--------
configurations | myself | integer | configurations.tp_transactions | normal
(1 row)

network=> select configurations.myself(myt.*) from myt;
ERROR: function configurations.myself(myt) does not exist
LINE 1: select configurations.myself(myt.*) from myt;
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.

network=> select configurations.myself(myt.*) from configurations.tp_transactions myt where trans_id=920787;
myself

12
(1 row)

I also tried creating the temp table first using this syntax and then inserting into it, but function still did not recognize the type.
network=> CREATE TEMP TABLE myt OF configurations.tp_transactions;
CREATE TABLE
network=> \d myt
