Fixed an issue where the async archiver would not be started if archive-push did not have enough space to queue a new WAL segment.

Browse Source 
This meant that the queue would never be cleared without manual intervention (such as calling archive-push directly). PostgreSQL now receives errors when there is not enough space to store new WAL segments but the async process will still be started so that space is eventually freed.

Reported by Jens Wilke.
