Marc G. Fournier	9d5c0af586	From: Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> ... Subject: [HACKERS] Aggregate function patches Here are the aggregate function patches I originally sent in last December. They fix sum() and avg() behavior for ints and floats when NULL values are involved. I was waiting to resubmit these until I had a chance to write a v6.0->v6.1 database upgrade script to ensure that existing v6.0 databases which have not been reloaded for v6.1 do no break with the new aggregate behavior. These scripts are included below. It's OK with me if someone wants to do something different with the upgrade strategy, but something like this was discussed a few weeks ago. Also, there were a couple of small items which cropped up in doing a clean install of 970403 (actually 970402 + 970403 changes since the full 970403 tar file appears to be damaged or at least suspect). They are the first two patches below and can be omitted if desired (although I think they aren't dangerous :).	29 years ago

Marc G. Fournier	e152661200	Fixes: ... It's bug in nodeAgg.c on lines 241, 242: null_array = malloc(nagg); for (i=0;i<nagg;i++) null_array[i] = 'n'; oneTuple = heap_formtuple(tupType, tupValue, null_array); - your query has not only aggregates but also 'group by-ed' fields and so null_array should contain tupType->natts elements (tupType->natts > nagg in your case). Patch follows and it's very simple. VAdim	30 years ago
