Thanks a lot.
vacuumlo did the job. Indeed there were more the 100.000 orphaned LOs in
pg_largeobject.
We have to check how we can avoid this by using contrib/lo or in general
without using LOs.
One last question. After using vacuumlo the file size of 16385/2613 is
still the same as before.
It seems the content has been removed but the file itself hasn't been
compacted.
Is there an option or tool which can do this as well ?
Ciao Dirk.
