postgresql - list Postgres ENUM type

Question

The suggested query to list ENUM types is great. But, it merely lists of the schema and the typname. How do I list out the actual ENUM values? For example, in the linked answer above, I would want the following result

schema         type      values
-------------  --------  -------
communication  channels  'text_message','email','phone_call','broadcast'

Answer 1

select n.nspname as enum_schema,  
       t.typname as enum_name,  
       e.enumlabel as enum_value
from pg_type t 
   join pg_enum e on t.oid = e.enumtypid  
   join pg_catalog.pg_namespace n ON n.oid = t.typnamespace;
