Tom,

It happened again. After doing the reindex, I did a vacuum full on the
pg_largeobject table. This time I did not get the TUPLE INDEX error but
the server terminated at the end of the vacuum command. The backend is
still running even though I get the error message:

aesop=# vacuum full verbose pg_largeobject;
NOTICE:  --Relation pg_largeobject-- blocks 21

server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

It consistently happens when I try to vacuum full the pg_largeobject
table. Is there anything I can get from the system to determine what is
happening?
Chris

Hm, those backend crashes should have left core dumps; can you get a
stack trace from the core?

            regards, tom lane
