Selecting Columns From a Record Variable (PostgreSQL 8.4) - function

Question

I'm trying to select a column from a record variable in a function I'm calling from an Update rule and am getting the following error:
'could not identify column "name" in record data type'
The following is what I'm doing to produce the error:
From within an Update rule:
SELECT * INTO TEMPORARY TABLE TempTable FROM NEW;
SELECT MyFunction();
From within MyFunction()
DECLARE RecordVar Record;
SELECT * INTO STRICT RecordVar FROM TempTable;
EXECUTE 'UPDATE AnotherTable SET column = $1.name' USING RecordVar;
Note: I realise that there are easier ways to achieve what the above code is achieving but I've simplified the actual implementation to focus on the problem I'm having, which has opened up other possible solutions but I'd really like to get the above code working if possible.

Answer 1

I just figured it out. Rather than inserting the columns from NEW into the Temporary Table, I insert the NEW record as a single column into the Temporary Table and refer to it as RecordVar."NEW" inside my function. My rule and function now look like this:
From within an Update rule:
SELECT NEW AS "NEW" INTO TEMPORARY TABLE TempTable;
SELECT MyFuction();
From within MyFunction()
DECLARE RecordVar Record;
SELECT * INTO STRICT RecordVar FROM TempTable;
EXECUTE 'UPDATE AnotherTable SET column = $1.name' USING RecordVar."NEW";

Answer 2

The second part could work like this:
DO
$BODY$
DECLARE
RecordVar TempTable;
BEGIN
SELECT * INTO STRICT RecordVar FROM TempTable LIMIT 1;
EXECUTE 'UPDATE AnotherTable SET column = $1.name'
USING RecordVar;
END;
$BODY$
Note how I use the table name as type. PostgreSQL automatically creates a composite type for every table in the system.
A variable holds one row, the SELECT can return many rows. All but the first will be discarded. I added LIMIT 1 to clarify the effect. I doubt that is what you want.
You probably shouldn't have to use a temporary table in a rule to begin with. You may want to post your complete setup ...
