Frank -

That is what I did and it was fine. But Vadim told me later
that all I really had to do was shutdown the server, restart it and
re-vacuum. You might try that first (you may also have to rm the
pesky pg_vlock in the ../data/base/whatever directory.

BlowawayRelationBuffers sounds ominous doesn't it? It turned out
not to be so bad in my case!
