## Visibility Timeout (vt)

pgmq guarantees exactly once delivery of a message within a visibility timeout. The visibility timeout is the amount of time a message is invisible to other consumers after it has been read by a consumer. If the message is NOT deleted or archived within the visibility timeout, it will become visible again and can be read by another consumer. The visibility timeout is set when a message is read from the queue, via `pgmq_read()`. It is recommended to set a `vt` value that is greater than the expected time it takes to process a message. After the application successfully processes the message, it should call `pgmq_delete()` to completely remove the message from the queue or `pgmq_archive()` to move it to the archive table for the queue.
