pg_dump crashes trying to dump database containing index on oid

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------

createdb snafu
psql -d snafu
CREATE TABLE test (test text);
CREATE INDEX idx_test_oid ON test (oid);
\q
pg_dump snafu

This sequence crashes while gathering index information with:
parseNumericArray: bogus number

This occurs because the 'indkey' field in the query used by pg_dump
contains a '-2', which crashes its Numeric Array parser.

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------

I believed the simplest fix would be to update the parser to handle the
negative numbers--cursory examination shows that it shouldn't be too
hard. On the other hand, there may be problems with creating indexes
on oids. This database worked just fine with Postgres 6.4.3
