No, there's nothing wrong with quote_literal. Your example is showing
that plpgsql converts a "null" composite value into a row-of-nulls,
when dealing with a variable of a named composite type (in this case,
the variable is the parameter "val"). This is arguably wrong, but plpgsql
has been doing that for a mighty long time so people are hesitant to
change it.
