Hi,
When I call pg_identify_object on a domain constraint, it produces an invalid identifier because it omits the 'domain' keyword.
For example, when running it against the us_postal_code_check constraint from the Create Domain documentation (PostgreSQL 8.4.22 Documentation) - I expect to receive "us_postal_code_check on domain public.us_postal_code", but I actually receive "us_postal_code_check on public.us_postal_code".
I've attached a script which demonstrates the issue, as tested on the postgres:latest docker image (Debian 15.1-1.pgdg110+1).
