Replacing data in Archive Enabled Tables using LOAD

Provide a default PLAN_TABLE and DSN_STATEMENT_CACHE_TABLE

If we use the CURRENT EXPLAIN MODE special register more widely, we have to create either a PLAN_TABLE and a DSN_STATEMENT_CACHE_TABLE or an ALIAS for each user. If we forget it, it doesn't work. So if there would be a default table for both, all ...
