[Postgres-xc-developers] still insert segment fault

[xiong w. <wan...@gm...>]

Hi Mason,

Take a look at the following cases:

postgres=# CREATE TABLE atest5 (one int, two int, three int);
CREATE TABLE
postgres=# INSERT INTO atest5 (two) VALUES (3);
server closed the connection unexpectedly
	This probably means the server terminated abnormally
	before or while processing the request.

postgres=# INSERT INTO atest5(three)  VALUES (3);
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.

Core was generated by `postgres: postgres postgres [local] INSERT
                              '.
Program terminated with signal 11, Segmentation fault.
