Hi, The function heap_page_prune (src/backend/access/heap/pruneheap.c) Has a comment:
"/* * presult->htsv is not initialized here because all ntuple spots in the * array will be set either to a valid HTSV_Result value or -1. */ IMO, this is a little bogus and does not make sense. I think it would be more productive to initialize the entire array with -1, and avoid flagging, one by one, the items that should be -1. Patch attached. best regards, Ranier Vilela
