I did this in response to a review comment (point #5): https://www.postgresql.org/message-id/20200219191636.gvdywx32kwbix6kd@development Tomas suggested a min of 1024, and I thought I was being more conservative choosing 256. Still too high, I guess? I can lower it. What do you think is a reasonable minimum? Regards, Jeff Davis
