Did you read it? > Here's the entire description: " pg_send_query() sends a query or queries asynchronously to the connection . Unlike pg_query(), it *can send multiple queries at once to PostgreSQL*and *get the results one by one using pg_get_result().* Script execution is not blocked while the queries are executing. Use pg_connection_busy() to check if the connection is busy (i.e. the query is executing). Queries may be cancelled using pg_cancel_query(). *Although the user can send multiple queries at once, multiple queries cannot be sent over a busy connection. If a query is sent while the connection is busy, it waits until the last query is finished and discards all its results.*" Any case, that's only workaround for mysql (mysqlnd) & postgresql. What about those that uses other RDBMS?
