from the development trunk to the XQFT branch
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2010/03/17 - tsheyar: compiler/algebra/properties.c,1.49
-- Introduced a new column-name-origin property that enhances the column names
in the DOT generated algebra plans. If a column stems from a ref_tbl or a
path step we now keep the original name throughout the plan.
(Use pf-option -fN to print the mapping of original names.)
-- Make property usage a little bit more defensive. Instead of !PFprop_icol
a new function PFprop_not_icol is introduced that copes correctly with
missing property information.
