OK, I ran:
postgres -O -P -D /cluster/location
reindex table pg_class;
backend> reindex table pg_class;
And then nothing returns. Nothing stating whether it was successful or a failure.
And then if I do:
bash-3.2$ postgres -O -P -D /shared/webapp/database webapp
I still get:
FATAL: cache lookup failed for index 2662

single-user backend, is to tell it to disregard system indexes
(-P command line option).
I wouldn't be too surprised if the corruption extends a lot further than
the one index :-( but maybe you will be able to extract something after
reindexing.
