That's a plpgsql function, not an sql function. Your other examples
look like they were taken from some other database that has different
extensions to the SQL spec than we do: there is no "varchar binary"
in Postgres, and we don't allow you to add random commas at the ends
of column lists. PG isn't going to like '0000-00-00' for a date,
either.
