Hi Everybody

Some more problems with Large Objects inside of my adt-functions:
(Postgres 4.1[including LO-patch], DECstation, ULTRIX 4.3)

When i create an empty database and want to retrieve 
the contents of the postgres class pg_large_object
i get the error message:

Query sent to backend is "retrieve (pg_large_object.all)"
Error: Unexpected identfier in dump_data: 

It doesn't matter if this class is empty. When i create some LOs
the effect is the same: I'm not able to read this class.

By the way: retrievals on pg_naming is OK.

To the postgressors:
I'm, working on LOs for several weeks now and i get more an more problems
with them (refer to my several mails in the last days, none of them were 
answered, or refer to the short list below)
Please could you tell me the actual state of LOs. Do they work
or not? And if not, what are the non-working actions.

short list of my last questions:
1. the LOcreat-function seems to pfree the memory of its
   first argument (the filename)
2. reading direct after writing seems not to be OK.
   When i create a dummy LO between the two actions it is OK.


Thanks Wolf
