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)
testdb=# create type test AS (a int , b int);
CREATE TYPE
testdb=# \dT+ test
List of data types

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:
