[SQL] pqReadData()

[Najm Hashmi]

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
