Modified files:
    doc/src/sgml   : runtime.sgml
    src/backend/optimizer/geqo: geqo_main.c
    src/backend/utils/misc: guc.c postgresql.conf.sample
    src/include/optimizer: geqo.h

Log message:
    Repair error apparently introduced in the initial coding of GUC: the
    default value for geqo_effort is supposed to be 40, not 1.  The actual
    'genetic' component of the GEQO algorithm has been practically disabled
    since 7.1 because of this mistake.  Improve documentation while at it.
