# Ticket #3762:  Make sure that an incremental vacuum that reduces the
# size of the database file such that a pointer-map page is elemented
# can be correctly rolled back.
#
# That ticket #3762 has been fixed has already been verified by the
# savepoint6.test test script.  But this script is simplier and a
# redundant test never hurts.
