Is there a reason why vacuum won't vacuum large objects? AFAIK they
are not really different from ordinary relations, and could be vacuumed
the same way. If you do a lot of lo_writes to a large object, its file
size grows without bound because of invalidated tuples, so it'd sure
be nice for LOs to be vacuumable...
Trying to force the issue doesn't work either:
lotest=> vacuum xinv150337;
NOTICE: Vacuum: can not process index and certain system tables
VACUUM
