Hi, actually what I was after was a continuous way to keep a
PostgreSQL db in sync with a changing MSSQL db.  Migrating
data from MSSQL to PostgreSQL is pretty easy.  The method
you described is one way.  The way we usually use is with
PgAdmin (a great tool) which has a Migration Wizard plugin
to automatically migrate a database from any ODBC source to
PostgreSQL (including tables and all).

Once the data is migrated, a method of syncing any updates
in the MSSQL db to the PostgreSQL db is what we require.
I haven't discovered a nice way of doing that yet.


ps: cc'd the pgsql-admin list back in to generate any
further discussion and ideas.
