Hi,

I don't know if this is the right place to ask this (and I'm sorry if
this isn't) but here is a little problem I encountered. I have been
using postgres in a redhat linux 6.1 for nearly 6 month and it has been
working fine until today. I have a table with a field called 'id'
(primary key) that is referenced from other tables. Today I tried to
delete one of the rows in this table with the following command (worked
fine a few weeks ago) and there's the output. It does that each and
every time I try to update the primary key or delete a row. I've stoped
and started the postmaster several times of course.

testsqc=> DELETE FROM henkilo WHERE id = 12;
pqReadData() -- backend closed the channel unexpectedly.
        This probably means the backend terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

Here's the output of the debug channel:

001108.16:31:16.753 [31195] StartTransactionCommand
001108.16:31:16.753 [31195] query: DELETE FROM henkilo WHERE id = 12;

etc...

Is this a known problem with a solution to it?

Thanks,
