Re: [PATCH] Add support for INSERT ... SET syntax

Hello all,

I am reporting a server crash encountered while testing the patch
provided by Suraj. The crash is consistently triggered by the query
attached below.

postgres=# INSERT INTO emp_test SET (empno,ename)=(SELECT 1,'aa');

server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

Thanks
Ajay
