This causes the generated triggers to log the changes into an
automatically created table named VTLOG_<q>_<o>_<table>, in the qualifier and
owner of the indexed table, where q, o and table are the qualifier, owner
and name of the table.
The changes accumulated into that table can be explicitly applied to the
index using the VT_INC_INDEX_<q>_<o>_<table> function.
