The Redshift extractor works by first discovering what tables and views are available to sync. This is done by querying information_schema to get table names, columns, etc. However, metadata on shared table views are not available so the extractor fails. Additionally, shared database is set up in its own database on Redshift and we cannot connect to it directly.
So in this PR we are replacing the
INFORMATION_SCHEMA.TablesbySVV_ALL_TABLESand replacingINFORMATION_SCHEMA.ColumnsbySVV_ALL_COLUMNSthat shows shared tables information.The only limitation that we still have is that we still didn't get the table constraints/PKs for shared tables.
