I think this also needs fixing in the pgsql RA. Because *every* time it 
is run, it calls:

pgsql_validate_all() {

     check_binary $SH
     check_binary $OCF_RESKEY_pgctl
     check_binary $OCF_RESKEY_psql

     return $OCF_SUCCESS
}

if ! pgsql_validate_all
then
     exit $OCF_ERR_CONFIGURED
fi

This is a problem

a) if Postgres is not installed
b) if Postgres is installed on a shared disc, which is not mounted yet 
(e.g. in a group configuration)
