You're going to have to manage this process carefully. I believe the
best tool for the job is pgloader:
http://pgfoundry.org/projects/pgloader/
It's certainly not inconceivable that this sort of tool could
automagically deduce encoding (albeit often inconclusively) in much
the same manor as modern web browsers attempt to when they have no
alternative. I don't see much demand for that though.
