I have found what the problem is. I simply neglected to make a conservative assumption about suffix truncation needing to add a heap TID to a leaf page's new high key in nbtsort.c (following commit dd299df8189), even though I didn't make the same mistake in nbtsplitloc.c. Not sure how I managed to make such a basic error. Andreas' test case works fine with the attached patch. I won't push a fix for this today. -- Peter Geoghegan
