pqReadData() -- backend closed the channel unexpectedly.

Hi,

how can I determine WHY this happens:

pqReadData() -- backend closed the channel unexpectedly.

The SQL was:

May 08 20:52:10 dbmagic[605] Failed:<PostgreSQLExpression: "UPDATE DIAGNOSE
SET CREATION_DATE = 'Thu Apr 22 11:01:55 1999 CEST', CREATION_USER =
'GUSTAV', VERWEILDAUER = 0, ART = 'Y', TEXT = 'Pulmonale Metastasierung',
AUFENTHALTNR = 68571, NR = 312659, OPNR = NULL, DAUERDIAGNOSENR = 1000002632,
MODIFICATION_USER = 'GUSTAV', MODIFICATION_DATE = 'Thu Apr 22 11:01:55 1999
CEST', ZEIT = 'Thu Apr 22 11:01:00 1999 CEST' WHERE NR = 312659">

+----------------------------------+----------------------------------+------
| art | varchar() not null | 1
| aufenthaltnr | int4 not null | 4

| nr | int4 not null | 4

This is with postgresql-6.4.2 on NetBSD 1.3.2/intel

Thanks in advance.
