So you have about 62000 distinct schemata in your db?
Imagine that the average enterprise has about 200 tables max,
and an average sized country has about 300 such companies,
including public sector, with 62000 tables you could blindly model
.... the whole activity of a whole country.
Is this some kind of replicated data?
Whats the story?
