Since 7.1.1 we've tried to make it do so.

<scratches head>  Odd.  There's only one query in pg_dump that touches
relhasoids, and it's set up to only be used when "remoteVersion >= 70200".
It seems to work here, too: I can dump from a 7.1 or even 7.0 server
with current pg_dump.  Would you burrow in there and see what's screwing
up the version-check code?

BTW, what happens if you leave off -i?  It shouldn't be necessary.
