I believe the attached patch incorporates all the ideas discussed in the
pghackers thread about using the current actual table size for planner
estimation purposes.  The patch is not complete yet because (a) I
haven't touched the documentation, and (b) some of the regression tests
fail because of changes in plans; those expected-output files will need
adjustment.

Any comments, objections?

			regards, tom lane
