pg_trigger and tgargs

I was wondering if someone could tell me if I have gotten the fields of
tgargs correct:

<unnamed>\000 -- Constraint name?

foreign_table_multi\000 -- table with foreign key(s)

primary_table_multi\000 -- table with primary key(s)

UNSPECIFIED\000 -- ??

foreign_int_1\000 -- 1st field in foreign key

primary_int_1\000 -- 1st field in referenced primary key

foreign_int_2\000 -- 1st field in foreign key

primary_int_2\000 -- 1st field in referenced primary key

Thanks
