Currently there is no way to restore a single database from a pg_dumpall short
of heavy parsing of the dumpall script. What I usually recommend to folks
(and do with our servers @ omniti) is to have a script that does a
pg_dumpall -g for the global objects and then individual pg_dump -Fc's for
each database in the cluster.
