Always apply the bulk-insert optimization when inserting from a table function.
-------------------------------------------------------------------------------

                 Key: DERBY-4789
                 URL: https://issues.apache.org/jira/browse/DERBY-4789
             Project: Derby
          Issue Type: Improvement
          Components: SQL
            Reporter: Rick Hillegas


Inserting from a table function is a lot like importing from a file:

1) Derby has limited visibility into the size of the external data source.

2) The user is often trying to import a large data set.

The import procedures assume that Derby should always apply the bulk-insert optimization when
importing from a file. The same assumption seems reasonable whenever a table function appears
in the source stream of an INSERT.
