Sigh...

I wonder if the same happened in Ubuntu, which would explain the many
reports similar to #778507.

I see three ways forward:
 a) Basically ignore the remaining cases and tell anyone who asks about
    the warning that he can safely remove the PidFile setting.
 b) Bump the version in the postinst check and hope it works this time.
 c) Remove the version check and unconditionally remove the PidFile
    setting, if it uses the default path.

Does anyone have preferences?

Best regards,
Andreas
