RES: RES: How to use PQconsumeInput and PQisBusy correctly ?

Thanks Tom,

One more question, today I'm using the syncronous functions, like PQexec,
so, my apps is frozen until the query to be finish.

I'm wondering

1) Use pqexec in a separate thread, wait the thread or call
PQgetCancel/PQcancel when user request that, or

2) Use PQconsumeInput/PQisBusy, in a non-thread program and wait for query
to be finish or user request their cancel.

What is the better one ?

Thanks
