Description

If user set a larget nvseg in statement level, the nvseg is greater than the guc nvseg per seg, rm won't report error. It will allocate according to nvseg per seg. But this cannot satisfy statement level nvseg. RM will timeout at last. This behaviors is not reasonable. We should error out directly and tell user if he wants the nvseg in statement, he must change the guc ( hawq_rm_nvseg_perquery_perseg_limit ) accordingly.
