I don't want to use the LargeObject API, because I want to make my
application easy to port to different DBMS. And since LargeObject API is
not in for example in JDBC for mySQL, I don't want to use it. 

Anyway, I have used it before, and I have noticed the following thing:
when I store an object, and then try to rewrite the object (the new
object is bigger), nothing huppens. Well, the size of the object
changes, but when I retreive the data from the object, it is unchanged
:-? (i.e. I get the original object, the first one stored).
I thing that is odd. Something simmilar huppens, when I reduce the size
of the object and write it. Except that the size of the LargeObject does
not change, it staies the same, as it was.

Do you have any idea, what is going on?

thanks,

RP
