Update of /cvsroot/monetdb/pathfinder/compiler/algebra/opt
In directory sfp-cvsdas-1.v30.ch3.sourceforge.com:/tmp/cvs-serv10454/algebra/opt
Modified Files:
opt_join_graph.c
Log Message:
-- 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.
