Update of /cvsroot/monetdb/pathfinder/runtime
In directory 23jxhf1.ch3.sourceforge.com:/tmp/cvs-serv30598
Modified Files:
Tag: Nov2009
pathfinder.mx
Log Message:
Maintain a sort of database schema version number which can be checked
to fix the database schema after an upgrade. We now use the absence
of this version number to trigger a removal of the old-style (pre
Nov2009) index.
