Обсуждение: pqReadData()

Hi all,I was trying to simply update single field in one of my tables as given
below:
fliprdb=#  update artist set extrinfo='independent' where artist_id=6;
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.

Anyone have idea where the problem is and how it can be fixed?
Thank you all in advance.
Regards.Najm

Hmm.  Looks like you hit a backend crash :-(.  Hard to say more with
only this amount of info.  What PG version are you using?  What is
the table's declaration?  There should be a core file from the backend
crash, in $PGDATA/base/fliprdb/core --- can you get a backtrace from
it with gdb?
