[Postgres-xc-general] segfault while adding delete datanode

[muayad y <mua...@ya...>]

Add/delete node works fine when table has ~ 9million rows, but segfault in heap_update when table gets bigger,  any idea help ? thanks in advance 

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