What's the reason? For an INSERT or UPDATE - check? You can use a
TRIGGER and check the NEW-structure. Or create a new type, based on the
table-structure. Than you can create your function.

test=# create type a as ( i int, j varchar(20), k date);
CREATE TYPE
test=*# create function my_a (IN foo a) returns int as $$begin return 1; end; $$ language plpgsql;
CREATE FUNCTION
test=*#
