I recieved this report of a failing set of queries:
BEGIN;CREATE TABLE a (i INT);INSERT INTO a VALUES(1);DECLARE acur CURSOR FOR SELECT * FROM a;FETCH acur;\q

It certainly looks like a simple set of queries.

If this is done in 8.0.X the server shows:FATAL:  block 0 of 1663/17230/58190 is still referenced (private 2,global
1)LOG: server process (PID 14655) exited with exit code 1LOG:  terminating any other active server processesLOG:  all
serverprocesses terminated; reinitializingLOG:  database system was interrupted at 2005-03-17 23:20:52 EST
 

In CVS HEAD this seems to hang the server session in a way I have not
determined, but shutting down the server is impossible unless you use
pg_ctl -m immediate stop.
