I noticed the performance hit when
hstorewas swapped out forjsonb. I tracked it down to the query which calculatedchanged_fields, and found that be reverting to using thehstore-operator I was able to recover most of that performance. It's still slower thanhstore, but the gap is significantly shrunk.No audit trigger: 9.7s
