Hello!
I think there's a change missing in simple_table_tuple_update that
works by accident, as true == 1 == TABLE_UPDATE_WAIT.
Maybe the values could use a different starting value instead of 1 to
surface possible issues?
+ * TABLE_DELETE_WAIT -- set if should wait for any conflicting
+ * update/delete to commit/abort
+ * TABLE_DELETE_CHANGING_PART -- set iff the tuple is being moved to
+ * another partition table due to an update of the partition key.
+ * Otherwise, false.
"Otherwise, false" seems like a leftover from the previous comment version?
tableam.h also have two leftover "wait == false" comments.
