| Description |
forces contiguous overflow blocks which exist in different internal tables to be compared and combined if possible.
In releases 6.1.0 and above, the overflow is split into a "safe" table which contains the largest available blocks, and the normal "b-tree" table which contains smaller blocks. After a crash, the "safe" table is used to recover the overflow to a known state. Because of this separation, it is sometimes possible to have blocks which appear to be numerically contiguous, but which are not combined because they exist in different tables. The "reblock-ovf" verb will correct this situation.
