Gday all,
I have a large database with many large objects, linked to a single table.
I have been trying to backup the database so I can migrate to a later
version, but the backup has been failing due to problems within
pg_largeobject. I am not surprised at these errors, because the server
is not protected by UPS and has had several power outages (I'm working
on this with the database owner!) over the past few years.
Recently I tried to perform a vacuumlo, as I thought this might clear up
the problems, and the process fails after a long time with the following
log:
F:\PostgreSQL\8.3\bin>vacuumlo -U xxx -W xxx
Password:
Failed to remove lo 317198793: ERROR: large object 317198793 does not exist
Failed to remove lo 4065905288: ERROR: current transaction is aborted,
commands
ignored until end of transaction block
Failed to remove lo 0: ERROR: current transaction is aborted, commands
ignored
until end of transaction block
F:\PostgreSQL\8.3\bin>
When I added the -v option, there were many "removing lo xxxxx" messages
before the above messages appeared. I have previously tried to reindex
pg_largeobject, but that process failed as well.
Can someone offer please offer some advice on how to resolve this?
TIA.
