There is. You have (at least) 2 other options:

1) In the "/etc/conf.d" files (as I tend to do):
# grep need /etc/conf.d/postgresql-9.5
rc_need="netmount"
(This means, postgresql-9.5 needs the 'netmount' service to have started first)

# grep need /etc/conf.d/netmount 
rc_need="net iscsid"
(This means, netmount needs 'net' and 'iscsid' started first)

2) /etc/rc.conf
See the following section in the default version:
===
# It's possible to define extra dependencies for services like so
#rc_config="/etc/foo"
#rc_need="openvpn"
#rc_use="net.eth0"
#rc_after="clock"
#rc_before="local"
#rc_provide="!net"
===
