Обсуждение: 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:
Jun  9 10:02:11 pihsi postgres[31547]: [19] LOG:  query: select count(*)

tilikartta where yritys=18231413;

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

In addition to the other messages, the above only defers deferrable
constraints.  If you didn't specify initially deferred or deferrable when
creating the fk constraint, the above will not affect it.
