      Description

      Somewhere along the line, working_tpch1_compareLogOnly/misc/pseudoColumns2.sql started locking up. The query

      select count(distinct idbPm(l_orderkey)*10000000 + idbExtentRelativeRid(l_orderkey)) from lineitem;
      

      Is the culprit. It can be reduced to

      select max(idbPm(l_orderkey)) from lineitem;
      

      and still cause the problem.

      However, if we shoot for a smaller dataset:

      select count(distinct idbPm(r_regionkey)) from region;
      

      All is well.

      This is a regression from 1.4.4
