Server process crashes when using count(field).

Hello.

Server process crashes when using count(<fieldname>), however it's ok when using count(*).

Look at this example :

netstat=> \d ruscan_current
Table "public.ruscan_current"
Column | Type | Modifiers
------------------+-----------------------------+-------------------------------------------------
...
sld_id | integer | not null default nextval('ruscan_serial'::text)
...
Indexes: ruscan_current_pkey primary key btree (sld_id),
...

netstat=> select count(*) from ruscan_current ;
count
--------
194672
(1 row)

netstat=> select count(sld_id) from ruscan_current ;
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
!>

That's All !

And there are no log messages with this configureation of logging :

server_min_messages = info
client_min_messages = info

There are only the following in logs :

I'm Using PostgreSQL 7.3.2 on FreeBSD-4.7-RELEASE-p7

configure :
./configure '--prefix=/slave/pgsql_7.3.2' '--with-perl' '--enable-integer-datetimes' '--enable-recode'

Thanks.
