Althoug this happens on old 6.5.3, I would like to know if this has
been already fixed...
Here is the scenario:
1) before vacuum, table A has 8850 tuples.
2) vacuum on table A makes postgres crashed.
3) it crashes at line 1758:
Assert(num_moved == checked_moved);
I examined variables using gdb. num_moved == 8849, check_moved ==8813, num_tuples == 18.
4) if PostgreSQL is not compiled with assertion, vacuum does not crash. However, after vacuum, the number of tuples
descreasesfrom 8850 to 8814!! (I am not sure which number is correct, though)
I think this is an important problem since a data loss might
happen. Any idea?
