Ashutosh Chauhan commented on HIVE-4394:
----------------------------------------
Aah.. second time in a day : ( I thought I ran some query but really it was
different.
Harish, you are right, postgres doesn't allow UDAF as an argument of another
UDAF, so above query doesn't run on pg. I checked pg docs which also says to
return NULL in case default is not defined. So, I think our new behavior is
consistent with all other implementations. I will upload the patch overwriting
.q.out file. Harish, can you take a look.
