Change planner to use the current true disk file size as its estimate of 

a relation's number of blocks, rather than the possibly-obsolete value
in pg_class.relpages.  Scale the value in pg_class.reltuples correspondingly
to arrive at a hopefully more accurate number of rows.  When pg_class
contains 0/0, estimate a tuple width from the column datatypes and divide
that into current file size to estimate number of rows.  This improved
methodology allows us to jettison the ancient hacks that put bogus default
values into pg_class when a table is first created.  Also, per a suggestion
from Simon, make VACUUM (but not VACUUM FULL or ANALYZE) adjust the value
it puts into pg_class.reltuples to try to represent the mean tuple density
instead of the minimal density that actually prevails just after VACUUM.
These changes alter the plans selected for certain regression tests, so
update the expected files accordingly.  (I removed join_1.out because
it's not clear if it still applies; we can add back any variant versions
as they are shown to be needed.)

* lazy_update_relstats - update pg_class statistics for a table or index
*
* We always want to set relpages to an accurate value. However, for lazy
* VACUUM it seems best to set reltuples to the average of the number of
* rows before vacuuming and the number after vacuuming, rather than just
* using the number after vacuuming. This will result in the best average
* performance in a steady-state situation where VACUUMs are performed
* regularly on a table of roughly constant size, assuming that the physical
* number of pages in the table stays about the same throughout. (Note that
* we do not apply the same logic to VACUUM FULL, because it repacks the table
* and thereby boosts the tuple density.)
*
* An important point is that when the table size has decreased a lot during
* vacuuming, the old reltuples count might give an overestimate of the tuple
* density. We handle this by scaling down the old reltuples count by the
* fraction by which the table has shortened before we merge it with the
* new reltuples count. In particular this means that when relpages goes to
* zero, reltuples will immediately go to zero as well, causing the planner
* to fall back on other estimation procedures as the table grows again.
*
* Because we do this math independently for the table and the indexes, it's
* quite possible to end up with an index's reltuples different from the
* table's, which is silly except in the case of partial indexes. We don't
* worry too much about that here; the planner contains filtering logic to
* ensure it only uses sane estimates.
