[GENERAL] Retrieving query results

 Hi, ALL,
[quote]
PQntuples

Returns the number of rows (tuples) in the query result. Because it
returns an integer result, large result sets might overflow the return
value on 32-bit operating systems.

int PQntuples(const PGresult *res);

Is there another way to not to overflow the result?

Thank you.
