FWIW this is pg_shdepend_reference_index which is actually a bit special. It's
a "shared" relation which means it spans all your databases. Your reindex
didn't rebuild to. To reindex it you would have to shut down postgres and run
REINDEX in postgres in "standalone" mode.

I think it would be more interesting to know how you got into this situation.
When you ran initdb did anything unusual happen? Is it possible anything later
truncated these files?

There's no reason I can imagine 8.3 would be any more susceptible to this than
8.2. And certainly no reason you would want to use a year-old release of 8.2
missing a year's worth of bug fixes and security fixes. The current release of
8.2 is 8.2.12.
