Hi list,

How can I list all values I gave to a type I created?

what kind of type -- an enum?

in psql, you can break down enums with \dT+

postgres=# create type foo as enum ('a', 'b', 'c');
CREATE TYPE
Time: 13.000 ms
postgres=# \dT+ foo
                      List of data types
 Schema | Name | Internal name | Size | Elements | Description
--------+------+---------------+------+----------+-------------
 public | foo  | foo           | 4    | a       +|
        |      |               |      | b       +|
        |      |               |      | c        |
(1 row)

getting auto increment id value

From

Hi,
    I have a table and it's only distinct value is it's auto incremented id.
I need to insert like 80.000 rows at ones so I have some time issues.
Problem is I need a way to get a return value which is id of my inserted row
since I need that id for another insert action. I think I should use a
function for this but I am not sure how I can get Id of my inserted row.
Thanks.

yeah...another way to do that is via psql -E, which echos internally
thrown queries to the console.

Use INSERT INTO tbl ... RETURNING your_auto_inc_column. See also the
docs for the RETURNING clause at:
  http://www.postgresql.org/docs/current/static/sql-insert.html
