Is that calling syntax correct? I'd think it should be:

SELECT foofunc(footable.*, 10) FROM footable;

Note there are two arguments to foofunc (in either version)

test=# SELECT version();
version
--------------------------------------------------------------------------------------------------------------------------------------
PostgreSQL 8.4.2 on i386-apple-darwin9.8.0, compiled by GCC i686-
apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5493), 32-bit
(1 row)

test=# CREATE TABLE footable(id int4, name varchar(10));
CREATE TABLE
test=# INSERT INTO footable (id, name) VALUES (1, 'foo'), (2, 'bar');
INSERT 0 2
test=# CREATE FUNCTION foofunc(a footable, b integer DEFAULT 10)
postgres-# RETURNS integer AS $$ SELECT 123; $$ LANGUAGE SQL;
CREATE FUNCTION
test=# CREATE FUNCTION foofunc(a footable, b numeric DEFAULT 10)
postgres-# RETURNS integer AS $$ SELECT 456; $$ LANGUAGE SQL;
CREATE FUNCTION
test=# SELECT name, foofunc(footable.*, 10) FROM footable;
name | foofunc
------+---------
foo | 123
bar | 123
(2 rows)

test=# SELECT name, foofunc(footable.*, 10.0) FROM footable;
name | foofunc
------+---------
foo | 456
bar | 456
(2 rows)

In any event, I couldn't get your example to work on Postgres 8.4
regardless due to the varchar2 type. Which version of Postgres are you
using?

test=# CREATE TABLE footable(id int4, name varchar2(10));
ERROR: type "varchar2" does not exist
