It looks like this bug has been fixed in a different way in the current
pg_dump sources (clearTableInfo now knows that sequences don't have the
standard attributes). It also looks like pg_dump has changed enough
since 6.1 that any patches wouldn't be easily transferred back and
forth anyway.
You might be able to run the current pg_dump against your 6.1 database
by recompiling the current pg_dump.c/.h/common.c atop the 6.1 libpq.
That should cure the protocol incompatibility. However, pg_dump is
friendly enough with the system table layouts that I fear it might not
work with an old database anyway.
Probably your best bet is just to go ahead and use your patched pg_dump
to extract data from your old database.
