spec_result_clear_result
dbClearResult() returns TRUE, invisibly, for result sets obtained from
dbSendQuery(),
dbSendStatement(),
or dbSendQueryArrow(),
An attempt to close an already closed result set issues a warning
for dbSendQuery(),
dbSendStatement(),
and dbSendQueryArrow(),
dbClearResult() frees all resources associated with retrieving
the result of a query or update operation.
The DBI backend can expect a call to dbClearResult() for each
dbSendQuery() or dbSendStatement() call.
