AlterTableCreateToastTable API still not right for pg_migrator

I just started reading the pg_migrator source code, and I notice that
we still didn't get AlterTableCreateToastTable's API right for
pg_migrator's usage. It needs to be exposing an option to force
a particular OID for the toast table. The way pg_migrator is handling
that now is both ugly and unsafe, and it's really pretty silly when the
underlying create_toast_table() function is perfectly capable of being
told what we want it to do.

There's still time to fix this before RC1. I propose adding
"Oid toastOid" to AlterTableCreateToastTable's arguments, with
the semantics that if it's not InvalidOid then we attempt to create
the toast table with that OID.

Fine with me. I can adjust pg_migrator to match. We did discuss this
in the past, and the current API is less than idea. I think we held off
on the change so we were not changing the API between betas. At the
start of RC1 seems fine and I will time pg_migrator's final release to
match RC1.

I have update pg_migrator CVS to match the new API, but I will not put
out a new pg_migrator release until Postgres 8.4RC1 is released.
