    src/backend/optimizer/geqo: geqo_main.c

    src/include/optimizer: geqo.h

Log message:
    Remove geqo_random_seed parameter.  Having geqo reset the global random()
    sequence every time it's called is bogus --- it interferes with user
    control over the seed, and actually decreases randomness overall
    (because a seed based on time(NULL) is pretty predictable).  If you really
    want a reproducible result from geqo, do 'set seed = 0' before planning
    a query.
