pidof not working for postgresql-8.3 ?

[Ennio-Sr <nasr(dot)laili(at)tin(dot)it>]

Hi all!
 
[Running Debian/Lenny powerpc on an iBook.]
After upgrading from postgresql-8.1 to pg_8.3 I lost the capacity to
connect to my databases. I have re-created them using old dump.out files.

Besides that I just found out that 'pidof' doen't seem to work for the
ordinary user, as far as postgresql is concerned, whereas it works
regularly for other processes:

user$ pidof /usr/sbin/apache
19095 19094 19093 19092 19091 19088

user$ pidof /usr/lib/postgresql/8.3/bin/postmaster
[nihil]

Is this a normal behaviour for the new pg_8.3?

Thanks for your attention.
Regards,
	Ennio.
