Description: Cannot get domain constraint names from psql
Details:
It would be nice to see domain constraint names in \dD output of psql
utility. Without this feature the only way to delete (or modify) constraint
is to do pg_dump -s (or use something like phpgadmin) to find out constraint
name and only after that issue ALTER DOMAIN .. DROP constraint statement.
Patch for adding this functionality is quite trivial, for example:
