Hi,

To build a threaded forum application I came up the following schema:

forum
------
id_forum | integer| not null default nextval('forum_id_forum_seq'::regclass)
id_parent| integer|
subject | text | not null
message | text |

Each message a unique id_forum and an id_parent pointing to the replied
post (empty if first post).

How can I build an elegant query to select all messages in a thread?

Thanks,
