Paul M. Aoki (aoki@acm.org) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
no way in LargeObject API to detect short read?

Long Description
org.postgresql.largeobject.LargeObject.read(byte[],int,int) returns void instead of int.  there's therefore no
reliable,non-exceptional way to detect short reads. 

the natural way to write blocked-read loops would be to assume that read(byte[],int,int) returned the number of bytes
reador (e.g.) -1 on EOF.
