Rather than configuring huge start timeout for the service, firing it
up and hoping for the best I was thinking about disabling start
timeout entirely, make service of type "notify" and signal service
readiness via sd_notify. Also update progress by sending STATUS
message when some significant stage of DB startup procedure finishes.
This is not solving watchdog problem, but I think it would be an
improvement anyway. At least, it would provide better debugability of
start-up of this particular service.
