PQclear ​

Function ​

PQclear is used to release the storage associated with PGresult. Any query result should be released by PQclear when it is no longer needed.

Prototype ​

void PQclear(PGresult *res);

Parameters ​

Table 1 PQclear parameter

Precautions ​

PGresult is not automatically released. That is, it does not disappear when a new query is submitted or even if you close the connection. To delete it, you must call PQclear. Otherwise, memory leakage occurs.
