I need to determine wheter to use lo_import for large objects.
There is implementation in ODBC used type named "lo" (comapring type
oid).  Type oid doesn't represent only large objects.

I agree with you except lo implementation in ODBC ;-)

Does it cover lo_export which need oid as second parameter?
I'm sorry I'm new in using large objects and creating new types.

Thanks a lot
