I suppose a better (though maybe not perfectly accurate) wording is that
setting up the pl/pgsql execution layer to trap "arbitrary SQL-layer
exceptions" is fairly expensive. Even if the user specifies specific
errors the error handling mechanism in pl/pgsql is code for generic
(arbitrary) errors being given to it.
