I don't think you ever mentioned exactly what platform you're running

The machine has two dual-core Xeon 5130 cpus. The os is openSUSE 10.2
(x86-64). The output of uname -a is:
Linux db2 2.6.18.8-0.7-default #1 SMP Tue Oct 2 17:21:08 UTC 2007 x86_64
x86_64 x86_64 GNU/Linux
Did I mention the PostgreSQL version is 8.2.5?
On my machine the corresponding lines point to /usr/lib64:
You are right. Of course the directory /usr/lib64 exists and contains
lots of shared libraries and other stuff, but indeed no directory perl5.
Maybe this is just a cross-distribution difference in file layouts,
but I'm suddenly wondering if there's a 32-vs-64-bit issue here.
Exactly which perl packages have you got installed?
rpm says: "perl-5.8.8-32". The somewhat lengthy output of "perl -V" is:

One more information about the current situation: Besides the processes
that are stuck in a statement (meanwhile I have five and the most recent
belongs to yet another user) I also see many idle connections. I'm
pretty sure that the users are out of office at the moment and their
workstations are shut down, so the connections should not exist at all.
Since I have now a total of 69 connections and already touched the
connection limit yesterday I will now restart the server. Thus, I won't
be able to provide any more detailed information until the problem
arises again.
Of course, I can still give you general information about the system.
Regards,
Christian
