Looks that way. This is fixed in 7.2, so you might want to think about
an update sometime soon.

You could modify contrib/pg_resetxlog to force a value at least 16384 into
the OID counter. Since the DB was evidently not shut down cleanly, I'd
counsel cutting out the xlog-reset function entirely; just make it read
the pg_control file, set a valid nextOid, update the CRC, and rewrite
pg_control.
