Modified files:
    src/backend/optimizer/path: costsize.c pathkeys.c
    src/backend/utils/cache: lsyscache.c
    src/include/utils: lsyscache.h

Log message:
    Planner failed to be smart about binary-compatible expressions in pathkeys
    and hash bucket-size estimation.  Issue has been there awhile but is more
    critical in 7.4 because it affects varchar columns.  Per report from
    Greg Stark.
