System columns not returned by certain table AM APIs

This leads to garbage values for xmin and cmin and an ERROR for xmax and cmax.

This is not an exhaustive list of operations for which we see this behavior:

  1. INSERT/UPDATE/DELETE..RETURNING <tx_column>,...
  2. SELECT <tx_column>,.. FROM ..;
