Re: backends die on pg_dump, and spurious files?

In accord with Murphy's Fifth Postulate, after being driven to send a
message to pgsql-admin, I have since solved the problem.  Thus, I send this
message to record the answers for posterity.

There were two bogus rows in the "users" table.  One with OID 0 and one
with OID 1634628924; how these rows got into the table I have no idea, but
they were filled with bogus data.  Deleting these rows and vacuuming fixed
the problems with this table (though I still see "no parent tuple" messages).

I just deleted all these spurious files.  (They were all of zero
length.)  I have no idea why they were created in the first place.

Now that I can pg_dump, time for PostgreSQL 7.0 beta 2!
