2009/10/06 - boncz: compiler/include/physical.h,1.56.6.2
enable heuristic rewrite value-selections in the algebra backend of
MonetDB/xQuery
has to properly implement pf:attribute(ctx, node, ns1, loc1, ns2, loc2)
first,
as only the verion without namespaces was there (that one is now gone).
many restrictions:
- only non-loop-lifted equality tests
- not involving fn:collection or pf:collection (as path reversal in the
latter will never find the supernode)
- not involving any date/time/etc typed expressions (as the indices only
work for string and numerical equality)
went through the testweb and fixed all apparant problems
note the Aug2009_NFI value indices are full; whereas previously they would
omit frequent data items
