Problem with very big queries.

Hello everybody.

I want to send to postgresql-8.0 a very big query,
select * from table where lala IN (....)
Inside IN there are almost 60000 values.

Unfortunately, the server terminates with a singal 11 and I get
to my console the following:

An I/O error occured while sending to the backend.
An I/O error occured while sending to the backend.

jdbc version is      8.0-322 JDBC 3.

Could anybody help?

Regards.
