It's the "pg_inherits: not found, but visible" thread in pghackers
on 3/20 and 3/21. Briefly, he had two separate occurrences of a table
file disappearing while the pg_class row remained (and he hadn't
tried to delete it, either). The only idea I can come up with is that
a removal of some other table removed the wrong file. Ugly.
Joel, can you give us any more info? Do you have a postmaster log of
the queries that were issued while this was happening?
