As a long-time user of Sybase SQL Server and it's later incarnation as
Adaptive Server Enterprise, I can confirm that the result of this
approach was often unsatisfactory from a user perspective. That is,
the discovery was not always made before shipping to customers. :-(
I have high hopes for pg_migrator, but the pg_dump | psql approach has
always worked well for us -- no surprises and no pain beyond the
resource management issues.
