Update of /home/projects/pgsql/cvsroot/pgsql/src/backend/optimizer/path
from hub.org:/home/projects/pgsql/tmp/cvs-serv59076/backend/optimizer/path

Modified Files:
allpaths.c

----------------------------- Log Message -----------------------------

Fix GEQO optimizer to work correctly with new outer-join-capable
query representation. Note that GEQO_RELS setting is now interpreted
as the number of top-level items in the FROM list, not necessarily the
number of relations in the query. This seems appropriate since we are
only doing join-path searching over the top-level items.
