Mladen,
Keep reading, it's further down.
>From the 8.1.7 SQL Reference Manual, under the ALTER TABLE entry
(top of page 8-36):
"If you specify KEEP, then the specified amount of space is kept and the remaining space is freed. When the remaining number of extents is less than MINEXTENTS, then MINEXTENTS is adjusted to the new number of extents. If the initial extent becomes smaller than INITIAL, then INITIAL is adjusted to the new size."

I don't understand. Here is what manual says:
deallocate_unused_clause
Use the deallocate_unused_clause to explicitly deallocate unused space at
the end of the table,
partition or subpartition, overflow data segment, LOB data segment, or LOB
index and make the
space available for other segments in the tablespace.
It's not supposed to change the characteristics of the initial extent.
Funny. I'll test it
at home.
