src/backend/optimizer/util: pathnode.c
Log message:
Use fuzzy comparison of path costs in add_path(), so that paths with the
same path keys and nearly equivalent costs will be considered redundant.
The exact nature of the fuzziness may get adjusted later based on current
discussions, but no one has shot a hole in the basic idea yet ...
