Listing flex tables

You can determine which tables in your database are flex tables by querying the is_flextable column of the v_catalog.tables system table. For example, use a query such as the following to see all tables with a true (t) value in the is_flextable column:

=> SELECT table_name, table_schema, is_flextable FROM v_catalog.tables;
     table_name      | table_schema | is_flextable
