c2f0d565f3 Now that hashjoin is reliable for large joins (knock on wood), 
remove optimizer's arbitrary limit on how large a join it will use hashing
for.  (The limit was too large to prevent the problems we'd been seeing,
anyway...)

0b8b1fe3aa Tighten coding in new_join_pathkey, which seems to be a hotspot 
for GEQO ...

605d84941d Clean up cost_sort some more: most callers were double-counting 
the cost of reading the source data.

7a7ba33536 Clean up some bogosities in path cost estimation, like 
sometimes estimating an index scan of a table to be cheaper than a
sequential scan of the same tuples...

11a0027e28 Fix nasty little typo that prevented get_cheapest_path_for_joinkeys 
from ever returning a path.  This put a bit of a crimp in the system's
ability to generate intelligent merge-join plans...

e91f43a122 Fix potential overflow problems when relation size exceeds 
2gig.  Fix failure to reliably put the smaller relation on the inside of
a hashjoin.

ff38837fe9 Fix nasty bug in optimization of multiway joins: optimizer 
would sometimes generate a plan that omitted a sort step before merge.

b204d10c79 Executor no longer cares about mergejoinop, mergerightorder, mergeleftorder, 
so remove them from MergeJoin node.  Hack together a partial
solution for commuted mergejoin operators --- yesterday
a mergejoin int4 = int8 would crash if the planner decided to
commute it, today it works.  The planner's representation of
mergejoins really needs a rewrite though.
Also, further testing of mergejoin ops in opr_sanity regress test.

8c3e8a8a0e From: Tatsuo Ishii <t-ishii@sra.co.jp> 
Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef
NOT_USED" for current. I have tested these patches in that the
postgres binaries are identical.
