RHDB just sits and does nothing?

Hi,

What an earth I am doing wrong? I am trying to delete about 6500 rows and
I am the only user connected to the database and it just sits there and
does nothing?

rahaks=# select count(*) from tilikartta where yritys=18231413;
 count
-------
  6347
(1 row)

rahaks=# explain delete from tilikartta where yritys=18231413;
                          QUERY PLAN
--------------------------------------------------------------
 Seq Scan on tilikartta  (cost=0.00..500.23 rows=249 width=6)
   Filter: (yritys = 18231413)
(2 rows)

rahaks=# begin foo
rahaks-# ;
ERROR:  parser: parse error at or near "foo" at character 7
rahaks=# begin;
BEGIN
rahaks=# set constraints all deferred;
SET CONSTRAINTS
rahaks=# delete from tilikartta where yritys=18231413;

Logs are fed to syslog and there I can see the following:

tilikartta where yritys=18231413;

It is now 10:09 local time and it still sits there and does nothing?
