PDO PgSQL: _pdo_pgsql_notice

Hi ! I'm reading the source of PDO PostgreSQL driver and i see that there's an empty function, _pdo_pgsql_notice, which is very interesting ! I think that it is used when PostgreSQL throw Notices. But, nothing is done... I want to know if somebody know why the content of the function is commented: static void _pdo_pgsql_notice(pdo_dbh_t *dbh, const char *message) /* {{{ */ { /* pdo_pgsql_db_handle *H = (pdo_pgsql_db_handle *)dbh->driver_data; */ } (line 98 of /etc/pdo_pgsql/pgsql_driver.c - PHP 5.2 - r272374) How can I store the content of "message" into a field of the PDOStatement ? I view that there's only a "pdo_dbh_t" param, I may just store this message into a field of the PDO class ? Thanks in advance. Samuel.
