8124a30f82 Bug fix: When the database file grows in size during a transaction, make sure 
the last page of the file gets written to disk even if that page is on the
free list and contains no data.  Otherwise the disk file will be too small
which can lead to database corruption in subsequent transactions. (CVS 643)

1cc093c2b5 Partial fix for a problem with LEFT OUTER JOIN. It used to be that the test 
for the right-hand table not matching the left table occurred after all
ON, USING, WHERE clause processing.  The test should occur after ON and
USING clauses are checked but before the WHERE clause is check.  This fix
works as long as the total number of "AND" separated terms in the ON, USING,
and WHERE clause does not exceed 32.  To do: make this work for any number
of terms and add test cases.

the same as in PostgreSQL and in Oracle. (CVS 600)
