[SQL] postmaster: init.d/start

[Markus Wagner]

Hi,

under SuSe Linux 6.3 there are different subdirectories rc<X>.d for
different runlevels. Each dir contains links to the start/stop scripts.
The filenames contain numbers to indicate the position / the order of
the services to start.

Where (for which runlevel) and at what position should I link the pg
start/stop script?
Why should one link it for more than one runlevel (I noticed this for
apache)?

Thanks,

Markus
