Hi,
I have another Problem when using LargeObjects.
From time to time, I get the exception
FastPath call returned ERROR: lo_lseek: invalid large obj descriptor (369)
What does this exception mean? It occurs randomly; a repeated
retrieval works usually.
The code I use here is appended below.
BTW, yesterday I posted another question, but that has not arrived at
the mailing list (even the retry after I subscribed). Is there any
problem with the list or does it just take some days to appear there?
Ciao
Ole
