JDBC driver build 215 slow when index contains column of type BIGINT

Hello!

I use PostgreSQL 7.4.6 and the JDBC-driver build 215. I have
a table of the form

create table business_case (
  bc_id BIGINT PRIMARY KEY,
  ...
);

To update a row, I use a PreparedStatement of the form

update business_case set ... where bc_id=?

I use setLong() to set the value of bc_id, but the update
is slow, as the index on bigint does not get used.

Changing the JDBC-driver to build 310 increases the speed dramatically:
160 updates with build 215 consumed more than 10 minutes, with build 310
just about 3 seconds.

Have I to do a typecast to ::bigint with build 215 in the PreparedStatement
to get the same performance as with build 310? That would be bad, as I
had to
form the PreparedStatement incompatible to other databases.

Regards,
Roland.
