Details:

Hi.

I'm trying to use blob fields (bytea) and have a curious problem with it (in
Delphi). When i'm store the blob stream into DB, the length is 810 bytes.
When i'm trying to get data from DB, gives me only 807 bytes. I was try to
store entire streams into files and locate differences. Three bytes aren't
be in exported file in the middle of the file :-O.
Can you look at this problem (i can send you these files).

PS : sorry for my poor english.
