Hello Adrian

when I run \dTS+ I get the same result as  \dT+

                            ^
testdb=# create type test AS (a int , b int);
CREATE TYPE
testdb=# \dT+ test
                 List of data types
 Schema | Name | Internal name | Size  | Description
--------+------+---------------+-------+-------------
 public | test | test          | tuple |
(1 row)

testdb=# \dTS+ test
                 List of data types
 Schema | Name | Internal name | Size  | Description
--------+------+---------------+-------+-------------
 public | test | test          | tuple |
(1 row)


Regards

So you want to get information from a user created type.
So you have two options:
1) Add a comment to the type:
COMMENT ON TYPE test is 'create type test AS (a int , b int)';

test=> \dT
                    List of data types
  Schema |  Name   |             Description
--------+---------+-------------------------------------
  public | ghstore |
  public | hstore  |
  public | test    | create type test AS (a int , b int)

2) Get the information from the pg_type system catalog.

test=> SELECT * from pg_type where typname='test';

I am not showing the output because it does not display well.


For more information on what is being returned take a look at:
