Issuing the followin SELECT crashes PG 7.0:

auction=# SELECT a.id,a.title,a.id,(select CASE WHEN a.stopdate < 'now' THEN 'closed' ELSE 'open' end) as status,to_char(a.time,'DD-MM HH24:MI'),b.price FROM auction* a, bid b WHERE a.id = b.auctionid AND b.login = 'mito2';
pqReadData() -- backend closed the channel unexpectedly.
        This probably means the backend terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
!# \q

Apparently PG doesn't like the (SELECT CASE ... ) statement, until I
added it everything went well. 

Here are the table descriptions:

                               Table "auction"
  Attribute   |   Type    |                     Modifier                     
--------------+-----------+--------------------------------------------------

 login        | text      | not null
 startdate    | timestamp | not null default now()
 stopdate     | timestamp | not null

             (stopdate > startdate)
             ((reserveprice ISNULL) OR (reserveprice > startprice))

                  Table "bid"
 Attribute |   Type    |        Modifier

The crash certainly is a bug, but you could get around it for now
by not using an unnecessary sub-SELECT.  Why not just
	...,a.id,(CASE WHEN ...
