2009/11/12 - boncz: compiler/semantics/heuristic.c,1.15.6.4
my batch of promised bugfixes for Nov2009
- disable prepared query mechanism for function-only queries (avoid mps!)
- make heuristic to use indices even more strict (not inside the where
clause
of a for-loop with >1 variables, as it may be a join).
- fix property bug in shredder (in case of tables with a single tuple,
being
appended to my a incremental multi-doc shred).
- fix simple bug (crash in printf format) in xrpc_client
