How to Examine a view

I have setup a view consisting of two tables and some compound fields.
Now I would like from the client perspective see what those compound
fields actually are originally.

Let's (for simplicity I have inlcuded only one table) say we have:
CREATE OR REPLACE VIEW clientview AS
 SELECT c.clientid, (c.orderer_name::text || ' :'::text) ||
substr(c.occasion::text, 1, 10) AS "Order occasion", c.customerid
   FROM client c

Is it possible to query postgres to tell me what field names and field
types "Order occasion" really consists of?
