Hi Randall,

Yep, I know what a rdbms blob is, I was just hoping there was a "Blob" class somewhere 
in a gambas component that I didn't know about that would allow access to the raw data 
from the gb.db translation of the blob into a string or whatever.

IIRC, recently there was a thread on a problem with postgresql v 9.2?? blobs that were being 
returned from the database as escaped strings.  One of my colleagues fixed that on our 
production database but woefully failed to document what the fix was.  I was just hoping to
be able to reproduce the problem on a test db and see if I could figure out from the raw data
exactly what the problem was and how to fix it forever, in case we need to do a db rebuild or 
whatever.

Bruce
