>Description:
        Consider pgsql_home in rc.conf is set to /var/db/pgsql, 
and home directory for user pgsql is /nonexistent.
After system start I always see

[kab00m@neo ~]$ ps ax|grep postgres
 683 ttyE0- I    0:00.08 /usr/pkg/bin/postgres -D /nonexistent/data 

Killing and restarting process it always run fine.

[root@neo kab00m]$ kill 683
[root@neo kab00m]$ /etc/rc.d/pgsql start
[kab00m@neo ~]$ ps ax|grep postgres
1166 ttyp0  S    0:00.07 /usr/pkg/bin/postgres -D /var/db/pgsql/data

>How-To-Repeat:
        cd /usr/pkgsrc/databases/postgresql84 && make install
        cp /usr/pkg/share/examples/rc.d/pgsql /etc/rc.d
        echo 'pgsql_home="/var/pgsql"' >> /etc/rc.conf
        echo 'pgsql=YES' >> /etc/rc.conf
        shutdown -r now
        ps ax|grep postgres
>Fix:
        Spent few hours to understand, no ideas.
