Please enter a FULL description of your problem:
- ------------------------------------------------
Unable to insert large objects into a table. Sometimes the backend dies,
sometimes it reports it is unable to create
the related xinv or xinx file.
Looking into pgsql/data/base/<tablename> reveals the files have been
created, and they are 16 Kb in size.


Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
- ----------------------------------------------------------------------
CREATE TABLE FOO (F OID);
INSERT INTO FOO VALUES (lo_import ('foo.ppm'));


If you know how this problem might be fixed, list the solution below:

OFFENDING STATEMENT */
1068             attptr += sizeof(int32);
