[Fwd: Re: 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?

and after a long wait...

DELETE 6347
rahaks=# commit;
COMMIT

It just took about three quarters of a hour to delete 6500 rows!
Something is definitely broken and probably I am the one who broke it. Any
guesses what I have broken and how I could fix this?
