Re: rc script to let a service wait for db available

Changing this to:
- - -
meteoavg_start() {
    /usr/local/bin/wait_for_pgsql.sh ${meteoavg_wfphost} ${meteoavg_wfpuser} ${meteoavg_wfpdb} "/usr/local/bin/${name} ${meteoavg_flags}" &
}
- - -
does not solve the issue. 
On system boot this script still blocks rc and prevents any other services from being started,
including the the jail with the pgsql server, where wait_for_pgsql.sh tries to connect.
