Try
select * from information_schema.domain_constraints;

The \dD view is already too wide IMHO, no need to make it wider for this.

However, your proposed patch points out something that seems to me to be
a bug in \dD: it produces multiple rows for the same domain, if said
domain has more than one constraint.  Surely that's confusing and
undesirable.
