bool pg_close ( resource connection)

pg_close() closes the non-persistent connection to a PostgreSQL database associated with the given connection resource. 成功回傳`TRUE`失敗回傳`FALSE`。

> 備注: Using pg_close() is not usually necessary, as non-persistent open connections are automatically closed at the end of the script.
