> Please enter a FULL description of your problem:
> ------------------------------------------------
> I developed an application in java.
> I storeed the file that has "-1" in the first position, using the
> Large Object Support function.
> However, when I load that file from the database as the "InputStream"
> class object, I was unable to read data until the file end.
> That is because the "read()" method of the "InputStream" class returns "-1".
>
>
>
> Please describe a way to repeat the problem. Please try to provide a
> concise reproducible example, if at all possible:
> ----------------------------------------------------------------------
> Please, compile the attacked program and execute this. (for example :
> java IOTest test)This program outputs the below.

> ================================================
> From DB 0:-1
> From DB 1:1
> From DB 2:2
> From File 0:255
> From File 1:1
> From File 2:2
> =================================================

> However, I think this outputs would be the below.

>
> "read()" method of "org.postgresql.largeobject.BlobInputStream" is
