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

Answer 1

If you have the table and column name, (but not the type name) use this:

SELECT pg_enum.enumlabel
FROM pg_type
 JOIN pg_enum ON pg_enum.enumtypid = pg_type.oid
 JOIN information_schema.columns ON information_schema.columns.udt_name =
                                    pg_type.typname
WHERE pg_type.typtype = 'e' AND
      table_name = $1 AND column_name = $2 ORDER BY pg_enum.enumsortorder

If you use enum_range on a column (in contrast to the other answers which used it on a type) it will return data for each row that exists, which is not what you want. So use the above query instead.
