$ret = $conn->sendQuery($string, $query)
Submit a query to Postgres without waiting for the result(s). After
successfully calling PQsendQuery, call PQgetResult one or more times
to obtain the query results. PQsendQuery may not be called again until
getResult has returned NULL, indicating that the query is done.
$result = $conn->getResult
Wait for the next result from a prior PQsendQuery, and return it. NULL
is returned when the query is complete and there will be no more results.
getResult will block only if a query is active and the necessary response
data has not yet been read by PQconsumeInput.
$ret = $conn->isBusy
Returns TRUE if a query is busy, that is, PQgetResult would block waiting
for input. A FALSE return indicates that PQgetResult can be called with
assurance of not blocking.
$result = $conn->consumeInput
If input is available from the backend, consume it. After calling consumeInput,
the application may check isBusy and/or notifies to see if their state has changed.
