Update of /home/projects/pgsql/cvsroot/pgsql/src/include/nodes
from hub.org:/home/projects/pgsql/tmp/cvs-serv7711/include/nodes
Modified Files:
relation.h
----------------------------- Log Message -----------------------------
Cache eval cost of qualification expressions in RestrictInfo nodes to
avoid repeated evaluations in cost_qual_eval(). This turns out to save
a useful fraction of planning time. No change to external representation
of RestrictInfo --- although that node type doesn't appear in stored
rules anyway.
