Benoit Besson I added some comments to the GitHub issue.

All in all, I still don't understand what you want to achieve here. The schema attribute is used to provide a specific schema. If you don't use that, then the default schema is used.

Therefore, just set the default schema at the database level, and you are done. Now, what do you want to achieve with SchemaExport dynamically? If you want to export the table structures and execute that on multiple schemas, it's better to strip the schema part and just rely on the current schema setting at the relational database level.
