Many thanks for your efforts which have been crowned with success at last!!
What remains inscrutable to me is why this problem did not arise
earlier. I cannot remember any changes that I have made to the system
recently. Or maybe it has been a defective update of the glibc? I did
not see in the bug report any hint about when this bug has been
introduced. Obviously it has something to do with the users having
disconnects, but we have been working with dial-up connections for many
years and did never see this bug.
By the way, does the "--enable-thread-safety" switch have anything to do
with the problem?

Phew, that might be hard work, but I will give it a try. Until I have
success I will probably restart the database server once in a week to
remove those old connections.
Thanks a lot for your help!
