Hi,
I've been trying to work with Large_Objects in Postgres for quite a
while now, trying to store or access them either from the monitor
or via LIBPQ.
Even though I've tried it in about a thousand different versions
it doesn't seem to work right. The documentation in Manual Section 7
is rather poor and the Example doesn't work either.
The closest I could get was that the some writing access was done to
"pg_largre_object" but the attemt to read it out failed.
A frequent error message was after the command:
inv_fd = p_open("/inv_file2", INV_WRITE, Inversion);
Error: Unexpected identifier: ?
so before I describe the whole mess in more detail:
1. Does anybody have experience with large objects who can explain
the access via LIBPQ or via the monitor.
2. Can anybody send me some example-programms for storing data in
large objects (in Unix as well as in in Inversion files).
Thanks in advance
Gunter
