We've found out, that the problem is in Delphi itself (and probably 
other Borland's products as well). Seems that Delphi components 
responsible for BLOBs handling call BDE incorrectly. We managed to 
make a workaround by calling BDE API manually instead of using 
components provided by Borland. It works, but make programming much 
more complicated, or at least much slower.

Unfortunately we are unable to compile this workaround into the 
components library to fix the problem because Borland/Inprise doesn't 
provide any source code for this part of their library.

Do you think we (PostgreSQL + Borland users) could influence Borland 
to solve this problem? They only need to include our routines into 
their library or just make some sorce code available (they released 
it for many other components in thier library) to allow us to fix it.
