Description

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

Prototype

void PQclear(PGresult* res);

Parameter

**Table 1** PQclear parameter
Keyword	Description
res	Object pointer that contains the query result.

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.
