This post was pretty much a complete waste of bandwidth then, seeing
that pggeneral never has a turnaround time as short as 15 min (it seems
to be more like 2 hours today :-().

However, if it happens again, please see what you can learn by attaching
to the stuck backend with gdb and getting a stack trace.
