Fred,
Automated solutions go from about 40% to 80% for the general case, but
not much higher, for reasons I am starting to believe have to do with
the fundamentals of computing. There's a proprietary thing from
EnterpriseDB that's supposed to be good, along with the open-source
things mentioned in this thread.
Are there a lot of things writing to the DB that need to be taken into
account? The FDW (foreign data wrapper) method works pretty well for
testing the read side in PostgreSQL, and allows you to use pretty
simple ways to import once you've done that testing.
Cheers,
David.
