Clear a result set
Frees all resources (local and remote) associated with a result set. In some cases (e.g., very large result sets) this can be a critical step to avoid exhausting resources (memory, file descriptors, etc.)
## S4 method for signature 'DatabaseConnectorResult' dbClearResult(res, ...)

dbClearResult() returns TRUE, invisibly, for result sets obtained from
both dbSendQuery()
and dbSendStatement().
An attempt to close an already closed result set issues a warning
in both cases.
