Okay, that makes sense. However, I noticed that ordering for system-header inclusions is somewhat random. For ex. nodeSubPlan.c, datetime.c, etc. include limits.h first and then math.h whereas knapsack.c, float.c includes them in reverse order. There could be more such inconsistencies and the probable reason is that we don't have any specific rule, so different people decide to do it differently. > > I think we shouldn't remove the extra line as part of the above change. > > I would take out the blank lines between our own #includes. > Okay, that would be better, but doing it half-heartedly as done in patch might make it worse. So, it is better to remove blank lines between our own #includes in all cases. -- With Regards, Amit Kapila. EnterpriseDB: http://www.enterprisedb.com
