The policy daemon (running under the Postfix spawn daemon) is started
when a Postfix SMTP server connects to its port. The Postfix SMTP
server will try to use that connection for several queries.

The Postfix spawn daemon assumes that its command will read from
standard input, and that it will write to stadard output and
standard error. If sqlgrey works that way then it can be run from
the Postfix spawn daemon. Otherwise you need a different solution.
