Database taking up space rapidly

Hi All,

I just moved over a db from 7.2.3 to 7.4.0 on a new RH9 server.

The dump, I remember was about 2GB, 350MB compressed, when I restored it
only about 3-4 days ago...

Now, the slice stands at about 30GB!!
/dev/sda2 50830616 30034872 18213700 63% /var/lib/pgsql

The server seems a bit slow in responding, and the Postmaster is taking
up a lot of CPU.

Here's where I find the bulk of the large files:

# pwd
/var/lib/pgsql/data/base/17142

Some of the files in this directory are:

-rw------- 1 postgres postgres 1073741824 Dec 23 18:57 17610
-rw------- 1 postgres postgres 1073741824 Dec 23 22:41 17610.1

-rw------- 1 postgres postgres 1073741824 Dec 25 00:55 17610.7
-rw------- 1 postgres postgres 1073741824 Dec 25 05:46 17610.8
-rw------- 1 postgres postgres 1073741824 Dec 25 10:58 17610.9

Not sure what's going on here...also vacuum analyzed the db a few
minutes ago.

Is there a way I can find out who is connected to the db and what
process is running under the postmaster?

Appreciate any help.

Thanks,
Anjan
