try this:

hostedused:
driver=accept
domains = +hosted_domains
condition = $lookup pgsql {\
                SELECT localpart from mailbox \
                WHERE domainname='${quote_pgsql:$domain}' AND \
                localpart = '${quote_pgqsl:$localpart}'\
                }
transport=hosted_delivery
cannot_route_message = Unknown mailbox


Or you could use a construct with $sg to make a colon-separated list from
the simpler query you had, as Stephen suggested already.

NB I didn't test this... please check my syntax and logic before implementing...
