That was something that bothered me too. I think in the patch as given,
the GUC parameter determining the logfile name would have to be
PGC_POSTMASTER, ie, you could not change it on the fly because the
backends wouldn't all switch together. There may be some finer-grain
timing issues as well.
On the whole I think that capturing all the backends' stderr via a pipe
and doing the file rotation in a single downstream process is a *much*
cleaner solution. However, I've been saying that right along and
haven't been listened to...
