Log Message:
-----------
> I enclose a short patch to reduce the PGARCH_RESTART_INTERVAL from 60
> seconds to 10 seconds. The original number was plucked from thin air
> some months ago, and I'd like to review that now based upon further
> thought, observation and experience.
>
> This change has little or no effect on performance, since the interval
> is there mainly to avoid repeated respawn attempts if archiver fails at
> startup. Archiver start-up time is very quick, so there is little danger
> of exceeding 10 seconds.
>
> On a busy system, if the archiver does die, then many files can build up
> in the 60 seconds before respawning. That xlog file backlog could take
> some time to clear. This then leaves a larger than normal window of data
> loss for a possibly long period.
>
> It's a minor change only, with no other effect on function.
